© 2017 American Physical Society. We have measured the K-shell internal conversion coefficient, αK, for the 88.2-keV M4 transition from the 106-day isomer to the ground state in Te127 to be 484(6). When compared with Dirac-Fock calculations of αK, this result agrees well with the version of the theory that incorporates the effect of the K-shell atomic vacancy and disagrees with the one that does not. As a byproduct of this measurement, we have determined the β branching from the isomer to be 2.14(3)%.
