摘要
采用γ -γ -t(HpGe -HpGe) 3参数快慢符合谱仪研究了10 1Tc β-10 1Ru的衰变 ,利用符合测量结果修正了10 1Tc β-10 1Ru的衰变纲图。实验首次观测到 174 .91、2 2 6.0 2、312 .4 0、4 0 8.77、4 17.91keV的γ射线 ,并确认其跃迁位置 ,同时确定了 616.3keVγ射线的跃迁位置。计算了各能级的β- 衰变强度和logft值。
The decay of 101 Tc to levels in 101 Ru has been studied using the three-parameter (γ-γ- t ) coincidence system of HpGe-HpGe detectors. From the coincidence data, a new decay scheme was constructed. The 174.91, 226.02, 312.40, 408.77 and 417.91keV gamma rays were observed for the first time and their transition scheme have been assigned, the transition position of 616.3keV gamma ray has been assigned at the same time. The intensities of β - decay and the values of log f t to most levels were calculated.
