We have measured the K-shell internal conversion coefficient, {alpha}{sub K}, for the 346.5-keV M4 transition in {sup 197}Pt to be 4.23(7). This result differs from a previous value, which disagreed significantly from theory. Our new value agrees well with Dirac-Fock calculations and removes the earlier discrepancy as a source of concern.
