能级密度参数经验公式的研究

Study of Semi-Empirical Formula for Nuclear Level-Pensity Parameter

本文研究了能级密度参数a的经验公式。应用系统学方法计算了(n,2n) 反应截面,并与实验结果比较,得到了较好的K值。

The semi-empirical formula for nuclear level-density parameter is studiedand the (n,2n) reaction cross sections calculated by using the systematicmethod,The measured values are compared with the systematic predictions,and the coefficient k for an optimized level-density parameter formula isobtained.
