采用Hartree-Fock(HF)+BCS方法，结合Skyrme相互作用和同位旋相关的接触对相互作用，系统地研究了中子和质子的奇偶质量差。配对相互作用的强度被确定为在质量表的大范围内重现经验的奇偶质量差。通过使用质子和中子的最佳参数集，我们用Skyrme相互作用和同位旋相关的接触对相互作用进行了全局(HF)+BCS计算。配对相互作用的强度被确定为在质量表的大范围内重现经验的奇偶质量差。利用质子和中子的最佳参数集，我们对原子核进行了整体HF+BCS计算，并与实验数据进行了比较。对于中等和重同位素的奇偶质量差，指出了配对相互作用的同位旋依赖性的重要性。用相同的模型系统地研究了质子和中子半径。
Neutron and proton odd-even mass differences are systematically studied with Hartree-Fock (HF) + BCS calculations with Skyrme interactions and an isospin-dependent contact pairing interaction. The strength of pairing interactions is determined to reproduce empirical odd-even mass differences in a wide region of the mass table. By using the optimal parameter sets for proton and neutrons, we perform global (HF) + BCS calculations with Skyrme interactions and an isospin-dependent contact pairing interaction. The strength of pairing interactions is determined to reproduce empirical odd-even mass differences in a wide region of the mass table. By using the optimal parameter sets for proton and neutrons, we perform global HF + BCS calculations of nuclei and compare them with experimental data. The importance of the isospin dependence of the pairing interaction is singled out for odd-even mass differences in medium and heavy isotopes. Proton and neutron radii are studied systematically using the same model.
