α粒子模型下的π^(±)──^(13)C弹性散射

π^(±)──^(13)C Elastic Scattering in α-particles Model

应用Glauber理论，假定13C核由3α核心和1价中子组成。计算了π(±)──(13)C在Tπ=162MeV的弹性散射微分截面。计算结果与实验值符合较好，说明α粒子模型是一很好的近似，同时指出，核心对截面的影响很重要。

Theπ(±)-（13)C elastic scattering cross section at 162 MeV is calculated by using the Glauber theory. The 13C is assumed to consist of one valence neutron and a core of three α-particles. A good agreement between the calculated results and experiments is obtairied. The results also indicated that the α-particle model is a good approximation and the important in fluence of the core on the cross section.
