摘要

在变形核的计算中验证了相对论平均场与密度相关介子-核子耦合的有效相互作用。利用相对论hartrei - bogoliubov (RHB)模型计算了稀土核区域内6个同位素链$(60\ensuremath{\leqslant}Z\ensuremath{\leqslant}70)$的基态性质，其中DD-ME1为平均场相互作用，Gogny D1S为配对相互作用。对总结合能、电荷同位素位移和四极变形参数的完全自洽RHB计算结果与现有经验数据进行了比较。

Ground-state properties of rare-earth nuclei in the relativistic Hartree-Bogoliubov model with density-dependent meson-nucleon couplings

The relativistic mean-field effective interaction with density-dependent meson-nucleon couplings DD-ME1 is tested in the calculation of deformed nuclei. Ground-state properties of six isotopic chains $(60\ensuremath{\leqslant}Z\ensuremath{\leqslant}70)$ in the region of rare-earth nuclei are calculated by using the relativistic Hartree-Bogoliubov (RHB) model with the DD-ME1 mean-field interaction, and with the Gogny D1S force for the pairing interaction. Results of fully self-consistent RHB calculations for the total binding energies, charge isotope shifts, and quadrupole deformation parameters are compared with the available empirical data.
