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。
Using Glauber’s theory, it is assumed that the 13C core consists of a 3α core and a monovalent neutron. The differential scattering cross sections of π (±) - (13) C at Tπ = 162MeV were calculated. The calculated results are in good agreement with the experimental data, indicating that the α particle model is a good approximation, pointing out that the influence of the core on the cross section is very important.
