用于热核同位旋效应研究的BGO探测器阵列

A BGO detector array used for Isospin Effect Research of Hot Nuclei

报道了35MeV/u ^(36)Ar+^(112,124)Sn反应中用于中等质量碎片(IMF)(3≤Z≤5)关联函数测量的ΔE(Si)+E(BGO)望远镜阵列的测试结果。实验表明该探测器阵列的几何安排有利于提高小角关联测量中的动量分辨,可用于IMF发射时标的同位旋依赖性的研究。

The small angle correlation function of the intermediate mass fragment in the reactions ^36 Ar ＋^112,124Sn at 35MeV/u were measured with an array of E（Si）＋E（BGO） telescopes. The resolution of the relative momentum is improved by the careful ealibration of the BGO scintillators in the current geometrical arrangement of the detector array. The experimental results show that this array is advantageous for the research of isospin effect on the emission time scale of intermediate mass fragments.
