THE EMISSION OF <i>L</i> RADIATION FOLLOWING INTERNAL CONVERSION OF γ-RADIATION IN HEAVY ELEMENTS

Abstract

The fluorescence yields of the L levels have been computed separately on the basis of radiation widths obtained from the work of Massey and Burhop, the widths of Auger transitions of the Coster–Kronig type measured by Cooper, and existing information on the widths of the L levels. In the case of fluorescence excitation, the total fluorescence yield calculated in this way is in general agreement with measurements of Lay. In the case of excitation by internal conversion of γ-radiation in the L levels, it is shown that the total fluorescence yield for elements in the vicinity of tantalum is appreciably less than the yield measured by Lay for fluorescence excitation, but that for the heavier elements near uranium, the yields should be comparable.
