Precise measurement of αK and αT for the 150.8-keV E3 transition in Cd111: Test of internal-conversion theory Academic Article uri icon

abstract

  • © 2016 American Physical Society. We have measured the K-shell and total internal-conversion coefficients, αK and αT, for the 150.8-keV E3 transition in Cd111 to be 1.449(18) and 2.217(26), respectively. The αK result agrees well with Dirac-Fock calculations in which the effect of the K-shell atomic vacancy is accounted for; it extends our precision tests of αK calculations to Z=48, the lowest Z yet measured. However, the result for αT disagrees by about two standard deviations from the calculated αT value, whether or not the atomic vacancy is included.
