¹⁰⁶Ag正宇称带结构研究

摘要: 利用能量为60 MeV的¹¹B束流，通过¹⁰⁰Mo(¹¹B,5n)¹⁰⁶Ag熔合蒸发反应布居¹⁰⁶Ag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¹⁰⁶Ag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πg_9/2_νh²_11/2(g_7/2/d_5/2)组态上的磁转动带。

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 πg_9/2_νh²_11/2(g_7/2/d_5/2) configuration.
