摘要
本文给出了在共振区光子穿透系数的表示式,它由三部份组成,分别对应复合核统计过程、复合核弹性散射道及非弹性散射道中的辐射退激过程.研究了在中子强度函数3s巨共振区13个偶中子核素的中子辐射俘获截面.中子能量范围为3MeV以下的共振区.结果表明,在同时考虑了统计和非统计过程后,可以解释实验测量的总俘获截面及γ能谱.
An expression for photon transmission coefficients in the resonance regions was given. The radiative neutron capture, which consists of both the statistical and nonstatistical contributions,for thirteen even-neutron nuclides in the 3s mass region were investigated in the resonance energy range less than 3MeV.
