测量了51.3MeV He 3在Ni 58和Ni 58（He 3，α）上弹性和非弹性散射的微分截面.弹性散射分析的光学模型与伍兹-撒克逊势。获得了几组令人满意的参数。包含一个自旋轨道项与V s 2.9 MeV改善了最佳拟合。在扭曲波近似下，利用复耦合，将非弹性散射事件视为单声子集体跃迁。β R 0′与其它实验得到的变形长度吻合较好。在具有不等的真实的和虚变形的计算中，发现2+角分布的拟合没有改善。利用先前获得的经验归一化，将（He 3，α））结果与零程畸变波预测进行了比较。光谱因子与其他实验和求和规则的期望值符合得很好。
Differential cross sections were measured for elastic and inelastic scattering of 51.3-MeV He 3 from Ni 58, and for Ni 58 (He 3, α). The elastic scattering was analyzed in terms of the optical model with a Woods-Saxon potential. Several satisfactory sets of parameters were obtained. The inclusion of a spin-orbit term with V s≃ 2.9 MeV improved the best fits. The inelastic scattering events were treated as one-phonon collective transitions in the distorted-wave approximation, using complex coupling. The β R 0′ agreed well with deformation lengths from other experiments. No improvement in the fit to the 2+ angular distribution was found in calculations with unequal real and imaginary deformations. The (He 3, α)) results were compared with zero-range distorted-wave predictions, using a previously obtained empirical normalization. The spectroscopic factors are in good agreement with other experiments and sum-rule expectations.
