摘　　要：利用逆运动学方法测量了碳靶在实验能量为35 MeV条件下13C的准弹性散射角分布。利用光学模型(Optical Model)对实验数据进行分析。在数据拟合得很好的条件下获得Woods-Saxon形式的光学势。在耦合通道法的框架内,非弹性通道在大角度下对实验数据的贡献是显著的,并对13C+12C的弹性散射或者准弹性散射进行了系统分析。目前表明,13C是一个正常的核,其半径并不异常大。The quasielastic scattering angle distribution of 13C of carbon target at 35 MeV/uncleon was measured by inverse kinematics method. The analysis of the experimental data was started using the optical model. The data are well reproduced and the Wood-Saxon optical potential is obtained. Within the framework of the coupled-channel method, the contribution of inelastic channels to experimental data at large angles is remarkable. The elastic/quasielastic scattering of 13C + 12C is systematically analyzed. The present work indicates shows that 13C is a normal nucleus and its radius is not unusually large.
