Progress on Measurement of Nuclear Decay Data

1.The Studies on the Decay Scheme of 72.3-D ~(160)Tb (SunPunan Hu Dailing Ding Zhaozhong) The decay scheme of ~(160)Tb has been studied with Ge(Li)detector and 105cm~3 Ge(Li)-110 cm~3 HpGe coincidence system.Forty-one gamma rays havebeen observed.The energies(in keV)and relative intensities of gamma raysfirst observed in this work are 148.7(0.026),319.4(0.018),728.0(0.033),and 1125.0(0.007).Gamma ray with energy 239.7 keV reported in literatureis excluded.On the basis of these results,the decay scheme of ~(160)Tb has beenconstructed.Two excited states in ~(160)Dy at 1408.8 keV and 1694.1 keV havebeen proposed.
