Gamma Rays ofRh106(130±2 min)

The gamma-ray spectrum of ${\mathrm{Rh}}^{106}$ (130 min) was studied with a NaI(Tl) crystal scintillation spectrometer of 9% resolution for the 662-kev gamma line of ${\mathrm{Cs}}^{137}$. The following gamma rays were obtained: 220±5 kev (18%), 435±5 kev (43%), 515±5 kev (100%), 610±5 kev (26%), 735±5 kev (36%), 820±5 kev (45%), 940±10 kev (?), 1070±5 kev (40%), 1225±5 kev (23%), 1380±10 kev (?), 1555±5 kev (23%), 1760±10 kev (7%), 1860±10 kev (8%), 2090±10 kev (1%), 2260±10 kev (1%). The measured half-life was 130±2 min.
