论文摘要
在变形的稀土上，弹性散射的角度分布$^{6} $ li在库仑屏障周围的能量上测量了变形的稀土$^{159} $ tb靶核。该反应的弹性散射横截面包括$^{159} $ tb的低谎言激发态的无弹性贡献。纯弹性横截面已从弹性和非弹性数据的混合物中提取。该系统的光学模型电位参数已从提取的纯弹性散射截面获得。已经使用这组潜在参数进行了耦合通道计算，以比较理论和实验性非弹性散射横截面。已扩展了这项工作，以从实验1N-pickup数据中获得$^{158} $ tb+n配置的光谱因子。
Elastic scattering angular distribution for weakly bound nucleus $^{6}$Li on the deformed rare earth $^{159}$Tb target nucleus has been measured at energies around the Coulomb barrier. The elastic scattering cross sections for this reaction consist of inelastic contributions from low lying excited states of $^{159}$Tb. The pure elastic cross-sections have been extracted from the admixture of elastic and inelastic data. The optical model potential parameters for the system have been obtained from the extracted pure elastic scattering cross sections. Coupled channel calculations have been performed with this set of potential parameters, to compare the theoretical and experimental inelastic scattering cross sections. The work has been extended to obtain the spectroscopic factor for $^{158}$Tb+n configuration from the experimental 1n-pickup data.
