| 摘 要： | 介绍在兰州重离子研究装置（HIRFL）上新建的一台用于超重核实验研究的充气谱仪装置，描述该装置的基本结构及设计参数。利用已知截面的反应175Lu(40Ar,4~5n)211,210Ac测试谱仪的性能，得到余核在不同He气气压下的电荷态分布，其平衡电荷态测量值与经验公式计算值符合较好。对于该反应，此实验条件下充气谱仪对余核的传输效率下限为14%。

| Abstract: | A new gas-filled recoil separator in HIRFL was introduced,which was dedicated to studies of the super-heavy nuclei.The configuration and technical parameters of the facility were described in detail.By using the complete fusion-evaporation reaction 175Lu(40Ar,4-5n)211,210Ac,the charge state distributions of evaporation residues in helium gas were measured at the different pressures.Experimental equilibrium charge states in the present work were deduced,which were well coincided with the calculation of empir... |
