Test of internal-conversion theory with measurements in Cs-134 and Ba-137 Academic Article uri icon


  • We have 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. Previous measurements of these K values led to a ratio that differed from calculated internal conversion coefficients. Our measured result, 30.01(15), disagrees with, but is a factor of three more precise than, the previous average of all experimental results. Our new result is consistent with calculations. 2007 The American Physical Society.
