摘　　要：介绍了利用Colver探测器测量γ射线的线性极化方法.用^(60)Co源对其进行测试,有效地测量了γ射线的电磁属性,从而确定了能级的宇称.We have investigated the performance of a EXOGAM-Segmented-Clover with 16 segments as a Compton polarimeter to measure the linear polarization of gamma rays. The polarization sensitivity of the Clover detector has been measured at the energy of 1332keV through the coincidence measurements of cascade gamma-rays from 6^60Co. Experimental values were in good accord with our expectation.
