Table of electronic factors for E0 electron and electron-positron pair conversion transitions

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, Omega(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, Omega(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 Omega(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. Crown Copyright (C) 2019 Published by Elsevier Inc. All rights reserved.
