| 摘 要： | 在相对论平均场理论框架下, 用NL-3和NL-Z两组相互作用参数研究了4个同位素链28Ni,54Xe,78Pt,94Pu的基态性质. 发现,在Hatree近似下奇A核结合能理论计算值与实验值的相对误差反而普遍比偶偶核小. 这说明用相对论平均场理论,即使不考虑矢量介子的空间分量,仍可以比较可靠地计算奇A核结合能.

| Abstract: | The ground state properties of the four isotope chains, 28^Ni, 54^Xe, 78^pt, 94^pu are studied in the relativistic mean-field theory by using two sets of parameters, NL-3 and NL-Z. We find that the binding energies of odd-A nuclei are even closer to the corresponding experimental results, compared with those of the even-even nuclei. Our results indicate that it is reliable to neglect the space component of the vector meson fields in calculating binding energies of odd-A nuclei in the relativistic mean-field theory. |
