The γ rays detected in two or more adjacent crystals within 400 ns were identified as a single γ ray scattered by the Compton effect whereas the energies detected in non- neighboring crystals or outside the 400-ns time window were regarded as independent γ-ray events. Timing of an addback γ ray were determined by the crystal with greatest energy deposition compared with neighboring crystals.
将下列参数保存到新ROOT文件
gt: 修正walk后的事件
ghit,gid, ge, gt: 原文件参数
ahit, aid, ae, at: 原文件参数
bhit, bid, be, bt: 新生成的addback
对比自己生成的addback与原文件参数
2.按照课件的做法从eurica.root建立二维对称矩阵。
ae和ge分别建立矩阵ge矩阵,对比ge矩阵和ae矩阵开窗谱的区别。3.按照Radware的方法,验证$^{152}$Eu的纲图中的每个分子内较强跃迁之间的符合关系,并验证左右两分支的gamma之间没有符合关系,并在$^{152}$Eu简化纲图(下图)的基础上进行扩展。
