摘要

用统计配分函数法计算了58Ni的核能级密度。基于从各种核势获得的真实单粒子能级方案的微观递归方法被用于去除各种简化近似，并准确地确定NLD。这些近似的效果是通过将该方法的结果与费米气体模型（FGM）的常见计算结果进行比较来确定的。根据现有的实验数据表明，这种完全微观的方法代表了NLD的行为。

Determination of nuclear level density based on a fully microscopic statistical partition function method for 58Ni

Nuclear level density (NLD) is calculated using the statistical partition function method for 58Ni. The microscopic recursive approach based on the realistic single particle levels schemes obtained from various nuclear potentials is used to remove various simplifying approximations and accurately determine the NLD. The effect of these approximations is determined by comparing the results of this method with the usual and common calculations of the Fermi gas model (FGM). It is shown that such a fully microscopic approach represents the NLD behavior according to the available experimental data.
