测量了入射能量为mev时晕核质子的弹性散射和破裂。利用Chapel Hill 89 （CH89）和Koning-Delaroche （KD）全球光学模型势（OMPs）系统地分析了不同能量下的弹性散射截面，并得到了相应的归一化因子。采用扩展版的连续离散耦合通道（XCDCC）形式，考虑了动态核心激励效应，对弹性散射和破裂数据进行了分析。研究发现，核激发在晕核的弹性散射和破裂反应中起着中等的作用，与前人在高能量下的结果一致。
The elastic scattering and breakup of the halo nucleuson protons at an incident energy ofMeV have been measured. Theelastic scattering cross sections at various energies, including the present one, are systematically analyzed with the Chapel Hill 89 (CH89) and Koning-Delaroche (KD) global optical model potentials (OMPs), and the corresponding normalization factors are obtained. An extended version of the continuum-discretized coupled-channels (XCDCC) formalism, including dynamic core excitation effects, is applied to analyze the elastic scattering and breakup data. It is found that the core excitation plays a moderate role in the elastic scattering and breakup reaction of the halo nucleus, being consistent with previous results at higher energies.
