摘要
使用相对论Ｔｈｏｍａｓ－Ｆｅｒｍｉ（ＲＴＦ）及相对论Ｈａｒｔｒｅｅ近似方法，在改进的标量微分耦合模型的基础上，计算了半无穷上核物质中张量耦合及ｍ。的变化对核表面性质与自旋－轨道耦合势的影响．结果表明张量耦合改善了标量微分耦合模型的自旋－轨道耦合势，但核表面张力系数及核表面厚度因张量耦合常数的增加而变小。
With the use of modified derivative scalar coupling (MDSC) model, the nuclear surface properties and the spin-orbit potential in semi-infinite nuclear matter have been investigated in the framework of relativistic Thomas-Fermi and Hartree approaches. Our results shoW that the spin- orbit potential has ben improved by the tensor coupling. However, the surface tension and the surface thickness are still too small. The effects of a-melon mass on the surface properties and the spin-orbit potential have also been discussed.
