Abstract
The total conversion coefficient, ..cap alpha.., of the ..gamma..-ray continuum has been determined as a function of ..gamma..-ray energy fom 0.5 to 2.5 MeV. The results are consistent with a mixture of E1 and E2 for E/sub ..gamma../ > or = 1.0 MeV, with a smooth increase of the E1 fraction with E/sub ..gamma../ up to approx. 1.5 MeV. At lower energy, in the upper half of the yrast region, ..cap alpha.. shows the expected dominance of E2 radiation, but for the lower half an increasing M1 contribution is found.
