AbstractAbstract
[en] Internal conversion coefficients (ICCs) obtained from relativistic self-consistent-field Dirac-Fock (DF) calculations are presented. The exchange terms of DF equations are included exactly, both for the interaction between bound electrons and for the interaction between bound and free electrons. Static and dynamic effects resulting from finite nuclear size are taken into account, the latter using the surface current model. Experimental electron-binding energies are used wherever possible. The hole in the atomic shell from which an electron was emitted is not taken into consideration because there is no compelling experimental evidence to warrant it. ICCs are given here for each Z between Z=10 and Z=126; for K, L1, L2, and L3 atomic shells; for nuclear-transition multipolarities E1... E5, M1 ... M5; and for nuclear-transition energies from ∼1 keV above the L1 threshold to 2000 keV. Also given are the total ICCs. Accurate (≤5%) experimental ICCs (K and total) are known for 77 transitions with multipolarities E2, M3, E3, M4, or E5. For these transitions, the theoretical DF values are, on average, about 3% lower than the theoretical relativistic Hartree-Fock-Slater (RHFS) values. The DF values are in better agreement with experimental results than the RHFS values
