Abstract

A new tabulation of electronic factors is reported for electron conversion for elements of Z from 5 to 126 and electronic factors for electron–positron pair conversion for elements of even Z from 4 to 100. The electronic factors for electron conversion, Ω_CE(E0), were calculated using a modified version of the CATAR program developed by Pauli and Raff with a relativistic-Hartree–Fock–Slater approach (Pauli and Raff, 1975). The electronic factors for electron–positron pair conversion, Ω_IPF(E0), were calculated using the model developed by Wilkinson (1969). The data tables presented here cover all atomic shells up to R2 and transition energies from 1 keV to 6000 keV and from 1100 keV to 8000 keV for pair conversion. A comparison with previous electronic factor tabulations is presented. Ratios of experimental Ω(E0) values for 83 E0 transitions in 8≤Z≤98 are compared to this tabulation. Two examples of how to use the tabulation to extract E0 strengths are also included.
