Polarization measurements of gamma radiation from sulphur-34

Abstract

Polarization measurements have been made on the gamma cascade in ³⁴S. The experimental results are consistent with a spin sequence 2⁺, 2⁺, 0⁺ with a mixture of MI and 1.5% of E2 in the first transition. The theoretical analysis of polarization-direction correlations with mixing included is discussed in some detail. Shell model assignments for the gamma cascade are given with possible explanations of the mixing ratio value obtained.
