对奇异核的Skyrme—Hartree—Fock计算

Skyrme-Hartree-Fock Calculation on Exotic Nuclei

用 Skyrme—Hartree—Fock 理论研究 Z=8和 Z=50附近同位素核的基态特性,在计算中使用了3套新的力参数 SK12、SK13和 SK14.计算结果表明,以上力参数的 Skyrme—Hartree—Fock 理论对这些核提供了一个很好的描述.在3组参数中,考虑同位旋有关的自旋-轨道力的 SK14参数是最好的,并且它还能够成功地得到 Z=50附近的核的电荷同位素移动.

The ground state properties of the nuclei near Z=8 and Z=50 are investigated using the Skyrme-Hartree-Fock approach with new force parameters SKI2,SKI3 and SKI4. The calculations show that the Skyrme-Hartree-Fock theory with above force parameters provides a good description on those isotopes.Among the three sets of force parameters, SKI4,which has considersed the isospin dependence of the spin-orbit force,is the best one.SKI4 is also successful in reproducing the charge shifts near Z=50.
