The decay of Se71
The decay of the 4.93 min-Se71 has been investigated using Ge(Li)-counters and a Ge(Li)-NaJ(Tl)-coincidence circuit. Se71 was produced by bombarding targets of GeO2 enriched in Ge70 with 55 MeV-α-particles. Chemical separation has been done. 8γ-transitions in the energy range from 147.2 keV to 1,265 keV have been found and their relative intensities have been determined. A level scheme for Se71→As71 having 6 levels is proposed.
