摘要
利用能量为60MeV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,建立了105Ag新的能级纲图,增加了26条新的γ跃迁和10条新能级．通过与其相邻同位素奇奇核的系统比较,对106Ag的4条转动带的组态及结构性质进行了初步讨论．
The high spin states of ^106 Ag have been populated via the ^100 Mo（^11 B,5n）^106 Ag reaction with a beam energy of 60MeV at HI-13 Tandem accelerator of China Institute of Atomic Energy. The gamma-gamma coincidences were measured using a gamma-ray detector array. By analyzing the gamma-gamma coincidence and their DCO ratios, the level scheme of ^106 Ag has been updated, in which twenty-six new gamma transitions and ten new levels are added. The rotational structure of ^106 Ag has been compared with its neighboring odd-odd isotopes and its configurations are discussed briefly.
