Precise measurement of alpha(K) for the 65.7-keV M4 transition in Sn-119: Extended test of internal-conversion theory Academic Article uri icon


  • We have measured the K-shell internal conversion coefficient, K, for the 65.7-keV M4 transition in 119Sn to be 1621(25). This result agrees well with Dirac-Fock calculations in which the effect of the K-shell atomic vacancy is accounted for and disagrees with calculations in which the vacancy is ignored. This extends our precision tests of theory to Z = 50, the lowest Z yet measured. 2014 American Physical Society.
