Internal conversion coefficients in Cs134, Ba137, and La139: A precise test of theory Academic Article uri icon


  • Recently we measured the ratio of K-shell internal conversion coefficients, αK, 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 αK 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.
