摘要
介绍了符合模式下γ射线的各向异性度测量方法以及由此来指定γ射线跃迁多极性的原理 .结合在具体物理实验中的探测器布局 ,讨论了影响此方法准确性的因素 .通过提取已知跃迁多极性的γ射线的各向异性度系数 ,说明了各向异性度方法是可靠的 .总结此方法与传统的角分布和DCO测量方法相比所具有的优越性 .
In order to assign γ ray multipolarity, a method of ADO ratios deduced from coincidence data has been described. The factors affecting the reliability of the ADO ratios have been discussed using an experimental detector configuration. The multipolarities for known γ rays deduced by the ADO method are consistent with the previous results obtained from γ ray angular distribution and DCO ratio measurements. This consistence proves that the ADO method is reliable. The advantages of the ADO method over the traditional DCO ratio measurement have been discussed.
