Test of internal-conversion theory with measurements in Cs-134 and Ba-137
MetadataShow full item record
We have measured the ratio of K-shell internal conversion coefficients, alpha(K), for the 127.5-keV E3 transition in Cs-134 and the 661.7-keV M4 transition in Ba-137. Previous measurements of these alpha(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.
