在相对论平均场（RMF）理论的框架下，计算了1315个10≤Z≤98的偶偶核的基态性质。计算中采用拉格朗日参数化NL3。配对相关性在Bardeen-Cooper-Schrieffer方法中被考虑。总结合能、均方根质子半径、均方根中子半径、均方根电荷半径、中子四极矩、质子四极矩、电荷（质子）六极矩、四极变形参数、六极变形参数的计算值见表1。对部分稀土核的RMF预测与现有实验资料进行了比较。
Abstract The ground-state properties of 1315 even–even nuclei with 10 ≤Z≤ 98 have been calculated in the framework of the relativistic mean-field (RMF) theory. The Lagrangian parametrization NL3 was used in the calculations. Pairing correlations are accounted within the Bardeen–Cooper–Schrieffer approach. The calculated values for the total binding energy, rms proton radius, rms neutron radius, rms charge radius, neutron quadrupole moment, proton quadrupole moment, charge (proton) hexadecapole moment, quadrupole deformation parameter, and hexadecapole deformation parameter are given in Table I. The RMF predictions of some rare-earth nuclei have been compared with the available experimental information.
