Mode d’emploi

1. Search by nuclide or by mass chain A.
2. Pick the 'Adopted Levels, Gammas' data set for recommended values, or an individual decay/reaction data set.
3. Read the comments: they explain how each value was obtained.
4. Download the ENSDF (80-column) or JSON format for programs.

Conseils

Cite the Nuclear Data Sheets evaluation of the mass chain (the reference is shown in the data set header).

1. Search XUNDL through the ENSDF search page (data-set type XUNDL).
2. Compare with the adopted ENSDF values to see what is new.
3. Follow the reference keynumber to the original paper.

Conseils

Use it to follow the newest spectroscopy; always cite the original article.

Contenu

Ground- and excited-state properties, decay radiations, charge radii, fission yields and more, with colour-coded charts of any property and links to the original evaluations.

Mode d’emploi

1. Choose a colour scheme (half-life, decay mode, Q values, radii…) and click a nuclide.
2. Use the side panels for levels, γ rays and decay radiation.
3. For programs use the API, e.g. https://nds.iaea.org/relnsd/v1/data?fields=ground_states&nuclides=100sn (CSV).
4. Other fields: levels, gammas, decay_rads (with rad_types=g, e, a, bp, bm…).

Conseils

The API sometimes refuses requests without a browser-like User-Agent header; the official Jupyter notebook shows how to use it from Python/pandas.

Mode d’emploi

1. Enter the radionuclide.
2. Read the table of emitted radiations with energy, intensity and energy per decay.
3. Export for dose or detector-efficiency calculations.

Conseils

Quick way to see all X-rays, Auger electrons and β spectra of a source in one table.

Contenu

Mode d’emploi

1. Pick an element from the periodic table.
2. Select the isotope for decay data and plots.
3. Check the evaluation source quoted on the page.

Conseils

Handy for a quick look; quote the underlying evaluation (ENSDF/ENDF) in publications.

Contenu

AME2020: atomic masses (mass excesses), binding energies, separation energies and reaction/decay Q values for ~3 500 nuclides with uncertainties and the input-data network. NUBASE2020: half-lives, spins, decay modes and excitation energies of ground and isomeric states.

Mode d’emploi

1. Download mass_1.mas20.txt (ME, binding energy/A, beta Q), rct1.mas20.txt and rct2_1.mas20.txt (reactions), and nubase_4.mas20.txt (states) as fixed-width text.
2. Read the column description: '#' replaces a decimal point for estimated values; '*' means unavailable. Retain separate flags for values and uncertainties.
3. Use published reaction uncertainties: evaluated masses are correlated. Adding individual mass errors in quadrature does not reproduce these uncertainties.
4. For quantities without a published reaction column, use the covariance file when applicable or explicitly label independent-error propagation.

Conseils

The chart's AME reference uses published energies and evaluated uncertainties where tabulated. New-mass and model calculations remain separate. Cite the original AME/NUBASE papers.

Mode d’emploi

1. Choose the isotope-specific PDF and record its revision date.
2. Check whether a linewidth means Γ or Γ/2π and whether wavelength is in vacuum before transferring a preset.

Conseils

The four D-line sheets list revision 2.3.4 (8 August 2025) at this check; cite the exact sheet and underlying measurement when needed.

Contenu

Evaluated atomic inputs and programs for plasma spectra, line lists and diagnostic calculations with documented versions.

Mode d’emploi

1. Choose the ion and database version, then follow a line-emission or diagnostic example.
2. Record temperature/density assumptions and check the atomic-data references for important transitions.

Conseils

Plasma excitation and ionization conditions differ from a cold trapped atom; do not transfer plasma emissivities into cooling presets.

Contenu

An intentionally selected handbook for H through Es, with persistent/strong lines, classifications and selected level tables; data-content update is November 2013.

Mode d’emploi

1. Open an element table or the wavelength finding list for a first identification.
2. For precision work follow the original references and compare the current ASD entry.

Conseils

A selected handbook is not a complete line list. This card links to NIST; it does not redistribute SRD tables.

Contenu

Line wavelengths, transition probabilities, level energies and ionization energies for atoms and ions.

Mode d’emploi

1. Enter the spectrum (e.g. 'Sn I' or 'Cs II') and wavelength range.
2. For electron binding energies of ions use the ionization-energies form.
3. Needed for laser spectroscopy and for ion-mass corrections.

Mode d’emploi

1. Search a constant by name.
2. Use the same CODATA version as the mass evaluation you compare with (AME2020 uses CODATA 2018).

Conseils

1 u = 931 494.10242(28) keV/c² (CODATA 2018).

Contenu

Recommended atomic weights and natural isotopic abundances with their variations.

Mode d’emploi

1. Open the element page.
2. Use the isotopic abundances for natural-target yields or reference-ion choice.

Conseils

NIST also offers a combined table of atomic weights and isotopic compositions.

Contenu

Mode d’emploi

1. Request fields=levels&nuclides=12c or fields=gammas&nuclides=12c from the documented service.
2. Join gamma start/end level indices to level idx; preserve evaluation cutoff and extraction dates.

Conseils

Gamma transitions and decay gamma radiations are different datasets. Blank uncertainty is unknown. The official guide describes a User-Agent header for HTTP 403 responses.

Contenu

A maintained-code repository and references to individual packages, alongside a clearly separated legacy-code collection.

Mode d’emploi

1. Follow the NSDD repository link and choose the program for the required evaluation task.
2. Read that program's manual, inputs, units and maintenance status; retain its version with results.

Conseils

A format or consistency check is not a new nuclear-data evaluation; legacy tools may require older compilers.

Contenu

Python models and fitting machinery intended for laser-spectroscopy analysis; source, examples and tests are available in the maintained repository.

Mode d’emploi

1. Start from an example matching the counting statistics and hyperfine model.
2. Fit shared A/B constants and centroids consistently across spectra; inspect correlations and residuals.

Conseils

Pin the version and report constraints, likelihood and frequency calibration; a converged fit alone does not establish correct spin or moments.

Contenu

The original package's spectrum models, χ² and maximum-likelihood fitting interfaces and tutorials; distinct from SATLAS2.

Mode d’emploi

1. Check the cited paper's software version before following its original example.
2. Record a reproducible environment and compare a migration to SATLAS2 against the old saved fit.

Conseils

Keep old and new APIs separate when reproducing the uranium CLS analysis; this card is for version lineage, not a second copy of SATLAS2.

Contenu

Documented modules cover physical functions, statistical analysis, modular spectra and coherent/dissipative interactions.

Mode d’emploi

1. Choose a tutorial for the intended King-plot, hyperfine-fit or simulation task.
2. Retain units, isotope references, input covariance and the installed version with your analysis.

Conseils

A King-plot line requires consistent isotope-shift signs and mass conventions; software cannot supply missing atomic field/mass-shift factors.

Comment citer

P. Müller and W. Nörtershäuser, Computer Physics Communications 311, 109550 (2025); doi:10.1016/j.cpc.2025.109550; cite the version used.

Contenu

Examples include optical molasses, magneto-optical traps, Hamiltonians, beams, magnetic fields and governing equations.

Mode d’emploi

1. Start with a documented Hamiltonian and one reproduced force or trajectory example.
2. Converge timestep, state basis and solver tolerance before interpreting temperature or capture.

Conseils

Choose the equation model explicitly; a rate-equation force calculation is not automatically a full coherent sub-Doppler simulation.

Mode d’emploi

1. Run the documented Basic Calculations notebook with a supported alkali atom.
2. Keep magnetic geometry, polarization and the chosen release fixed when comparing experimental transmission.

Conseils

The weak-probe model is not a saturated-cooling model. Read release-specific Python/GUI compatibility notes before installation.

Contenu

Fetches atomic levels and transitions and computes quantities such as lifetimes, polarizabilities and saturation intensities.

Mode d’emploi

1. Follow the Atom/State/Transition example for a selected atom.
2. Inspect which measured transition rates are present before using derived lifetimes or saturation intensity.

Conseils

Missing transitions can make a derived lifetime incomplete. Follow NIST data-use terms; the catalogue links to the service without mirroring its database.

Contenu

Solvers and examples for Hamiltonian evolution, dissipation and quantum states; a general numerical framework rather than an evaluated atomic database.

Mode d’emploi

1. Specify the basis, Hamiltonian and collapse operators before running a quantum-optics tutorial.
2. Check normalization, limiting cases and basis/tolerance convergence, then record the version.

Conseils

Mode d’emploi

1. Enter target, projectile and ejectile.
2. Read Q, threshold and their uncertainties.

Conseils

Check which mass evaluation the calculator uses.

Mode d’emploi

1. Use 'Stopping/Range Tables' for quick values.
2. Use TRIM for degraders, gas cells and implantation profiles.

Conseils

Essential for designing degraders before gas cells (IGISOL, CSC).

Contenu

Potential-array field solver with Lua user programs for time-dependent voltages (RFQ, traps, MR-TOF).

Mode d’emploi

1. Define electrodes (GEM files), refine the arrays.

Mode d’emploi

1. Select the database matching the quantity and search the atom/ion.
2. Read the cited paper's method and uncertainty before using a number in a spectroscopy model.

Conseils

A bibliography entry is a reference, not a recommended numerical value; distinguish theoretical and experimental papers.

Contenu

A concrete CLS example connecting scan voltage, relativistic Doppler conversion, shared hyperfine fits and statistical/systematic uncertainties.

Mode d’emploi

1. Read the beam/voltage convention and Tables 1–3 before reproducing a transition.
2. Keep isotope-shift direction and separate statistical/systematic errors; follow the associated raw-data record.

Conseils

The paper does not extract new absolute radii through a King plot: too few isotopes were studied and atomic factors remain necessary.
