Further test of internal-conversion theory with a measurement in (197)Pt
MetadataShow full item record
We have measured the K-shell internal conversion coefficient, alpha(K), for the 346.5-keV M4 transition in (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.
