Abstract
We have measured the -shell and total internal conversion coefficients (ICCs), and , for the 109.3-keV transition in to be 185.0(40) and 350.0(38), respectively. Previously this transition's ICCs were considered to be anomalous, with measured values lying below calculated ones. When compared with Dirac-Fock calculations, our new results show good agreement. The result agrees well with the version of the theory that takes account of the -shell atomic vacancy and disagrees with the one that does not. This is consistent with our conclusion drawn from a series of measurements on high multipolarity transitions.
