Internal conversion calculations in hartree-fock atomic model: Improved agreement with experiment

On the reliability of the theoretical internal conversion coefficients

“…Anyway these quantities are known for several particular transitions only (e.g. [11,14]). And in any case, such an 'error' would be a systematic rather than statistical one.…”

“…For some combinations of subshell and multipolarity they do not exceed 0.5%, for the remaining ones there are graphs in [12]. In [11], an extensive comparison of HF model 1 ICC with experimental ones was performed. Altogether 57 experimental data items for 8 transitions in six different isotopes were examined.…”

“…In the late 1970s, the most extensive tables [1,2] appeared where the pure HFS model was applied. Approximately, at the same time the first ICC based on the true Hartree-Fock (HF) model (without the Slater exchange term) were calculated [10,11]. To complicate things yet more, it is not clear whether the 'hole' in the atomic shell remaining after the conversion electron should be taken into account or not.…”

“…Recommendation. If you are using the conversion coefficient for a subshell which is not completely filled do not forget to rescale it following equation (11). If you are studying a transition in a deformed nucleus, think about the possibility of intranuclear conversion.…”
