摘要:

的曲率修正项的表面张力被用来作为一个标准的Skyrme相互作用在描述表面特性的效率。从核状态方程出发,计算了零温核饱和密度附近97个标准Skyrme相互作用参数组的表面张力系数的曲率修正项。其主要思想是找到那些参数化,使托尔曼的$δ$校正接近可用的理论预测,从统计理论。在97个模型中,只有59个模型给出了令人满意的结果。比较所获得的结果与不同的宏观和微观约束Skyrme参数化的实施结果在文献中,使我们能够选择4个模型,满足所有的约束。

英文摘要:

The curvature correction term to the surface tension is used as a criterion for the efficiency of the Skyrme interaction in describing surface properties. Based on the nuclear equation of state, the curvature correction term to the surface tension coefficient is calculated for 97 standard Skyrme interaction parameter sets in the vicinity of nuclear saturation density at zero temperature. The main idea is to find those parametrizations that give the Tolman's $δ$ correction close to the available theoretical predictions from the statistical theory. Only 59 out of 97 models give satisfactory results. Comparison of the obtained results with the results of the implementation of different macroscopic and microscopic constraints to Skyrme parametrizations available in the literature allows us to select 4 models that satisfy all the constraints.
