data.nuclides

Nuclide data.

The nuclides dataset contains information on all known nuclides, providing data on nuclear structure and decay modes across 118 elements. There is data here on natural abundances, atomic mass, spin, half-life, and more. The typical users for such a dataset include researchers in fields such as nuclear physics, radiochemistry, and nuclear medicine.

Details

This is a dataset with 3,383 rows and 29 columns.

  • nuclide: The symbol for the nuclide.
  • z, n: The number of protons and neutrons.
  • element: The element symbol.
  • radius, radius_uncert: The charge radius and its associated uncertainty. In units of fm.
  • abundance, abundance_uncert: The abundance of the stable isotope as a mole fraction (in relation to other stable isotopes of the same element). Values are provided for the nuclide only if is_stable is "TRUE".
  • is_stable: Is the nuclide a stable isotope?
  • half_life, half_life_uncert: The nuclide’s half life represented as seconds.
  • isospin: The isospin, or the quantum number related to the up and down quark content of the particle.
  • decay_1, decay_2, decay_3: The 1st, 2nd, and 3rd decay modes.
  • decay_1_pct, decay_1_pct_uncert, decay_2_pct, decay_2_pct_uncert, decay_3_pct, decay_3_pct_uncert: The branching proportions for the 1st, 2nd, and 3rd decays (along with uncertainty values).
  • magnetic_dipole, magnetic_dipole_uncert: The magnetic dipole and its associated uncertainty. Expressed in units of micro N, or nuclear magneton values.
  • electric_quadrupole, electric_quadrupole_uncert: The electric quadrupole and its associated uncertainty. In units of barn (b).
  • atomic_mass, atomic_mass_uncert: The atomic mass and its associated uncertainty. In units of micro AMU.
  • mass_excess, mass_excess_uncert: The mass excess and its associated uncertainty. In units of keV.
