TABLE 1 lists all nuclides [1] and isomers with half-lives >1 ms for which some experimental data are available. The data are taken from the Nuclear Wallet Cards (Tuli 2000) and from the Evaluated Nuclear Structure Data File (ENSDF 2002). The nuclides are listed according to increasing atomic number, i.e., they are grouped by elements. The data blocks for each element are arranged according to increasing mass number of the isotopes concerned.
| Column 1: | Atomic number Z. |
| Column 2: | Mass numbers A of corresponding isotopes. |
| Column 3: | Element symbol; the isomer excitation energy in keV units is attached in parentheses to the element symbol whenever applicable. |
| Column 4: | Half-life or level width. The uncertainty in the least significant digits is shown in parentheses. |
| Column 5: | Spin and parity J ?. Parentheses indicate that the assignment is uncertain. |
| Column 6: | Decay energies (Q-values) for beta minus ( ? ?),), electron capture ( ?) alpha (a), and proton (p) decay from Audi and Wapstra (1995). Systematic values are shown in square brackets. Decay modes and percent branchings BR are given for ? ?, ?+ ? +, IT (isomeric transition), and SF (spontaneous fission) decay; ?, p, n, or heavy-ion emission; as well as for ? ? or ? delayed n, p, ?, or SF emission. For stable nuclides the IUPAC isotopic compositions... |
