【摘要】利用能量为60MeV的11B束流,通过100 Mo(11B,5n)106 Ag熔合蒸发反应布居106 Ag的高自旋态,用15台带BGO反康的HPGe探测器进行在束γ谱学测量。通过γ-γ符合矩阵开窗分析和DCO比值分析,建立新的106 Ag能级纲图。根据正宇称带(1)不存在旋称劈裂,且具有较大的B(M1)/B(E2),初步指定其为建立在πg9/2ν[h211/2(g7/2/d5/2)]组态上的磁转动带。更多还原

【Abstract】 The high spin states of 106Ag were studied via the 100Mo(11B,5n)106Ag reaction with beam energy of 60 MeV at HI-13 Tandem Accelerator in China Institute of Atomic Energy.A new level scheme of 106Ag was presented.Band(1),which has large B(M1)/B(E2) value and no signature splitting,is assigned to the magnetic rotation band based on the πg9/2ν[h211/2(g7/2/d5/2)] configuration.更多还原
