摘　　要：采用γ－γ－ｔ三参数快慢符合谱仪研究了^（１０１）Ｍｏ■^(101)Tc的衰变，利用符合 测量结果构造了一个新的^（１０１）Ｍｏ■^(101)Tc衰变纲图．首次确定了１０４．７０， １０５．９５，７７４．１５ｋｅＶ γ射线的位置．首次观测到１５０８．０１ｋｅＶ的γ射线并确认了 其跃迁位置．The decay of ~101 Mo to levels in ~101 Tc has been studied using the three-parameter (γ-γ-t ) coincidence system of HpGe-HpGe detectors. From the coincidence data, the new decay scheme was constructed. The previously reported 104. 70, 105. 95 and 774. 15 keV γ rays were Observed, and have been assigned to the decay scheme for the first time. A newly observed 1508. 01 keV γ ray has also been assigned to the scheme for the first time. The－ tensities of β and the values of log ft to most levels were calculated.
