标题： Iso-scalar liquid drop model

摘要： 应用了一种新的液滴模型，该模型的体积项和表面能项具有同位旋平方的依赖性，用于再现核素实验已知的质量，其中质子数和中子数大于或等于二十。 考虑了基态微观能量校正。 尽管该模型仅有六个可调参数，但质量再现的质量良好，与其它当代质量模型相当。 此外，使用Myers和Swiatecki的地形定理评估的锕系核的裂变势垒高度接近数据。 显示英文摘要

摘要： New liquid drop model with the isospin-square dependence of the volume and surface energy terms is applied to reproduce experimentally known masses of nuclei with number of protons and neutrons larger or equal to twenty. The ground-state microscopic energy corrections are taken into account. In spite of the fact that the model contains only six adjustable parameters, the quality of mass reproduction is good, and it is comparable with other contemporary mass models. Also, the fission barrier heights of actinide nuclei evaluated using the topographical theorem of Myers and Swiatecki are close to the data.
