Abstract

An “internal conversion coefficient spectrometer” utilizing Ge(Li) and Si(Li) detectors has been used to make precision measurements of relative gamma-ray intensities for transitions following the decay of 192Ir and 207Bi, relative internal conversion line intensities for some transitions from 192Ir, and conversion coefficients for some transitions from the decays of 51Cr, 137Cs, and 192Ir. Limits and values are given for E2M1 mixing ratios and penetration effects for the 320.1-keV transition in 51V, the 484.5-keV transition in 192Os, and the 604.4-keV transition in 192Pt. The consequences of the results for nuclear structure are discussed.
