Abstract

The α-optical potential is one of the key input parameters used to measure the reaction rate of the (γ, α)-process using the Hauser-Feshbach statistical model and the principle of detailed balance. α-elastic scattering experiment on 113In p-nucleus was carried out in the energy range Elab = 26−32 MeV. The vacuum evaporation technique was used to prepare the 113In target (∼86 μg cm−2). An energy-dependent local optical potential parameters set was obtained by analysing the experimental elastic scattering angular distribution data. The local potential parameters are extrapolated for lower energies and are used to calculate the 113In(α, γ) reaction cross-section.

研究 113In(α, α)弹性散射以确定与天体物理γ过程相关的α-光势

α光势是利用豪瑟-费斯巴赫统计模型和详细平衡原理测量（γ，α）过程反应速率的关键输入参数之一。在 Elab = 26-32 MeV 的能量范围内对 113In p 核进行了 α 弹性散射实验。实验采用真空蒸发技术制备 113In 靶件（∼86 μg cm-2）。通过分析实验弹性散射角分布数据，获得了与能量相关的局部光学势参数集。在较低能量下推导出的局部光势参数用于计算 113In(α, γ)反应截面。
