Multipole mixing ratios of transitions in175Lu populated from the decay of175Hf

Abstract

Electron capture decay of175Hf(70 d) provides a possibility for unambiguous determination of the sign and magnitude of multipole mixing ratios for 89 keV and 114 keV transitions in175Lu. This is because both gamma rays are in coincidence with the 230 keV transition which is of a pureE2 character. The results of theγ —γ directional correlation measurements, in terms ofE2/M1 mixing ratiosδ, areδ 89 = 0.11±0.07 andδ 114 = 0.465±0.005. In addition the directional correlation measurements of the 89γ- 343γ and 319γ-114γ cascades yieldδ 343 = 0.08±0.07 andδ 319 = −0.152±0.015.Radioactivity 175Hf from174Hf(n, γ); measuredγ —γ(θ) deducedδ(E2/M1); Ge(Li) detectors.
