Internal conversion coefficients in Cs-134, Ba-137, and La-139: A precise test of theory Academic Article uri icon


  • Recently we measured the ratio of K-shell internal conversion coefficients, K, for the 127.5-keV E3 transition in Cs134 and the 661.7-keV M4 transition in Ba137. We here report a measurement of the 165.9-keV M1 transition in La139, based on which we convert our earlier ratio measurement into individual K values for the transitions in Cs134 and Ba137. These results continue to confirm the Dirac-Fock calculations of internal conversion coefficients that incorporate the atomic K-shell vacancy. 2008 The American Physical Society.
