abstract
In a research program aimed at testing calculated internal-conversion coefficients (ICCs), we have made precise measurements of K values for transitions in five nuclei, (197)Pt, (193)Ir, (137)Ba, (134)Cs and (119)Sn, which span a wide range of A and Z values. In all cases, the results strongly favor calculations in which the final-state electron wave function has been computed using a potential that includes the atomic vacancy created by the internal-conversion process.
