Test of internal-conversion theory with a measurement in 111Cd

Test of internal-conversion theory with a measurement in 111Cd

We have measured the K-shell and total internal conversion coefficients for the 150.8-keV E3 transition in 111Cd: αK = 1.449(18) and αT = 2.217(26) respectively. The αK value agrees well with Dirac-Fock calculations, in which the effect of the K-shell atomic vacancy is included. It is consistent wit...
