Level Scheme ofGa69

Abstract

The gamma-ray spectrum from the decay of ${\mathrm{Ga}}^{69}$ has been studied with the aid of a lithium-drifted germanium detector. Gamma rays of energy 2023, 1922, 1893, 1576, 1525, 1349, 1335, 1206, 1107.2, 1052, 871.8, 788, 763, 587, 573.4, 553, 532, 511, 320, and 237 keV have been observed. A new level scheme consistent with gamma-gamma coincidence measurements is presented for ${\mathrm{Ga}}^{69}$. The experimental results are compared with a calculation of the energy levels in ${\mathrm{Ga}}^{69}$ based on the intermediate-coupling model.
