利用统计磨蚀模型研究了中子皮厚度对周边核碰撞的影响。研究了不同中子皮厚度核的反应截面、中子（质子）去除截面、单中子（质子）去除截面及其比值。结果表明，这些观测值与丰中子核的中子皮厚度之间存在良好的线性相关。（一）中子和质子的去除截面之间的比率被认为是最敏感的可观察的中子皮厚度。分析表明，该比值的相对增大可以用来确定丰中子核的中子皮尺寸。
Effects of neutron skin thickness in peripheral nuclear collisions are investigated using the statistical abrasion ablation (SAA) model. The reaction cross section, neutron (proton) removal cross section, one-neutron (proton) removal cross section as well as their ratios for nuclei with different neutron skin thickness are studied. It is demonstrated that there are good linear correlations between these observables and the neutron skin thickness for neutron-rich nuclei. The ratio between the (one-) neutron and proton removal cross section is found to be the most sensitive observable of neutron skin thickness. Analysis shows that the relative increase of this ratio could be used to determine the neutron skin size in neutron-rich nuclei.
