Abstract

Abstract In this paper, we report on internal conversion coefficients for Z=111 to Z=126 superheavy elements obtained from relativistic Dirac–Fock calculations. The effect of the atomic vacancy created during the conversion process has been taken into account using the so called “Frozen Orbital” approximation. The selection of this atomic model is supported by our recent comparison of experimental and theoretical conversion coefficients across a wide range of nuclei. The atomic masses, valence shell electron configurations, and theoretical atomic binding energies required for the calculations were adopted from a critical evaluation of the published data. The new conversion coefficient data tables presented here cover all atomic shells, transition energies from 1 keV up to 6000 keV, and multipole orders of 1–5. A similar approach was used in our previous calculations [T. Kibédi, T.W. Burrows, M.B. Trzhaskovskaya, P.M. Davidson, C.W. Nestor Jr., Nucl. Instrum. Methods Phys. Res. A 589 (2008) 202] for Z=5–110.
