Using relativistic band structure calculations applying the relativistic linear muffin-tin orbital (RLMTO) method the internal conversion coefficient (ICC) for valence electrons of hcp-Tc-99 and bcc-U-235 are calculated. This coefficient describes the probability for a virtual delta-quantum of energy h-OMEGA (2.17keV for Tc, 77eV for U) emitted by a nucleus to eject an electron from the valence band (photoelectron emission with the photon source inside the solid). The resulting ICC's are very similar to the corresponding density of states.
