Description

The continuum γ-ray spectrum from the 173Yb(3He, α) reactions with E(3He) = 45 MeV has been studied. Below 4 MeV of excitation energy the γ-decay is mainly governed by K-selection rules. The γ-decay in the excitation region from 4 to 8 MeV can be described by two factors: (i) a γ-dependent term Enγ with n = 4.2 ± 0.4 and (ii) the Fermi-gas level density with level-density parameter a = (18.4 ± 1.9) MeV-1. There exist significant local deviations from the gross structure described by these two parameters. (orig.)
