本工作通过重离子融合蒸发反应124Sn(7Li,5n)126I布居了双奇核126I的高自旋态,入射束流由中国原子能科学研究院HI-13串列加速器提供,能量为48MeV。探测阵列由14套BGO-HPGe反康谱仪组成,通过在束γ谱学进行研究。实验用靶为浓缩124Sn((97.5±0.2)%)自支撑金属薄膜,厚度为4.6mg/cm2。实验共收集到9.42×107个γ-γ符合事件,各个Ge探测器利用133Ba和152Eu进行了能量刻度和效率刻度。数据离线处理将记录到的γ-γ符合事件反演生成对称化Eγ-Eγ矩阵,并
In this work, the high spin state of double-odd nuclei 126I is deposited by the heavy ion fusion evaporation reaction 124Sn (7Li, 5n) 126I, and the incident beam current is provided by the HI-13 tandem accelerator of China Institute of Atomic Energy. The energy is 48 MeV. The probe array consisted of 14 sets of BGO-HPGe anti-spectrum spectrometers, which were studied by beam gamma spectroscopy. The experimental target was to concentrate 124Sn (97.5 ± 0.2)% self-supporting metal film to a thickness of 4.6 mg / cm 2. A total of 9.42 × 107 γ-γ coincidence events were collected in the experiment, and each Ge detector used 133Ba and 152Eu for energy calibration and efficiency calibration. Data Offline Processing The recorded γ-γ coincident events were inverted to generate the symmetric Eγ-Eγ matrices
