Directional correlation of γ transitions inGe72following the decay ofGa<

Abstract

Directional correlations of coincident gamma transitions in Ge have been measured following the P decay of Ga (T~y2 --14.1 h), using a spectrom'eter consisting of a Ge(Li) and a Ge detector. The measurements were carried out for 16 gamma cascades populated in Ge, three of which measured for the first time. The results permitted definite spin assignments to the levels at 3325 keV (3 ) and 3342 keV (2 ). In addition, several previous spin assignments to other levels in " Ge were confirmed.

Low-lying states and isospin excitation in the Ge isotopes

“…Therefore their structure may be described by vibrational models, at least in the low energy region. However many experiments and theoretical work found that the low lying level structure of those nuclei is not a simple vibrator [18][19][20][21] . As a typical isotope in this area, the Ge isotopes present a useful testing ground for nuclear structure calculations.…”
