We further formulate the momentum distribution of a fragment in the halo nucleus scattering . its detailed expressions in the elastic dissociation process with considering the final - state interaction and the inelastic dissociation process without considering the final - state interaction are obtained , respectively 进一步还详细推导了晕核散射的碎片动量分布(包括纵向、横向动量分布) ，得到了考虑末态相互作用的弹性分离过程和不考虑末态相互作用非弹性分离过程的晕核散射碎片动量分布。
Nuclear scattering results in the displacement defects in material as well as the deflection of proton from its incident direction ; electronic stopping of protons acts as the most important factor in the degradation of incident proton energy , resulting in electronic effects such as single event upset 核散射是导致入射质子运动方向改变以及缺陷产生的主要因素，入射质子与核外电子云的作用是高能质子在材料中慢化的主要因素。核反应在宇宙高能质子引起的单粒子效应中有重要影响。
The optical - limit glauber theory has been of great success in describing the stable nucleus scattering at high energies . as it is extended to the nucleus scattering at low and intermediate energies , the modification of the coulomb field to the effective impact parameter and the diffuseness of the nucleon - nucleon ( n - n ) scattering in the forward direction has to be taken into account 其中光学极限近似的glauber模型能很好地描述高能小角度的稳定核散射，进一步推广应用于研究中低能稳定核散射时，需要考虑库仑相互作用对有效碰撞参数的修正和核子?核子两体散射在朝前方向的弥散。
