A nuclear mass formula based on the macroscopic microscopic approach is proposed, in which the number of model parameters is reduced compared with other macroscopic microscopic models. The root mean square (RMS) deviation with respect to 2314 training sets (measured nuclear masses) is reduced to 0.447 MeV, and the calculated value of each nucleus is no more than 0.8% different from the experimental value. The single and two nucleon separation energies and the shell gaps are calculated to test the model. The shell corrections and double magic number of superheavy nuclei are also analyzed.

改进的宏观微观质量公式

提出了一种基于宏观微观方法的核质量公式，与其他宏观微观模型相比，减少了模型参数的数量。2314个训练集（实测核质量）的均方根（RMS）偏差降低到0.447 MeV，每个核的计算值与实验值相差不超过0.8%。计算单个和两个核子分离能和壳间隙以测试模型。还分析了超重核的壳修正和双幻数。
