论文摘要
核模型计算中的光电位参数是通过拟合弹性散射数据来确定的。由于库仑部分的主导地位，弹性散射以更高的能量进行。建议使用（$α$，n）反应的另一种方法来确定适合天体物理相关的低能区域的α光势。已经选择了质量区域的P-Nuclei的反应，大约$ 92-168，并通过拟合（$α$，n）反应数据获得了修改后的McFadden-Satchler $α$光势。还通过分析（$α，γ$）横截面研究了水平密度和$γ$ ray强度函数的效果。
Optical potential parameters in nuclear model calculations are determined by fitting elastic scattering angular distribution data. Due to the dominance of Coulomb part, elastic scattering is performed at much higher energies. A different approach using ($α$,n) reaction is suggested to determine the alpha optical potentials suitable for astrophysically relevant low energy regions. Reaction on p-nuclei in the mass region A $\approx$ 92-168 have been chosen and a modified McFadden-Satchler $α$-optical potential is obtained from fitting the ($α$,n) reaction data. The effect of level density and $γ$-ray strength function is also studied using this new potential by analyzing ($α,γ$) cross-sections.
