发展了具有密度相关介子-核耦合的连续介质中的变形相对论 Hartree-Bogoliubov 理论。简要介绍了该公式，重点是用分波法处理轴向变形系统中的密度相关耦合、介子场和势。以富中子核$^{38}$Mg为例，新开发的代码通过球面相对论连续体Hartree-Bogoliubov计算进行了验证，其中仅考虑了密度的球面分量。当自洽地包含变形时，结果表明密度相关耦合强度的球形分量占主导地位，而低阶变形分量的贡献不可忽略。
The deformed relativistic Hartree-Bogoliubov theory in continuum with the density-dependent meson-nucleon couplings is developed. The formulism is briefly presented with the emphasis on handling the density-dependent couplings, meson fields, and potentials in axially deformed system with partial wave method. Taking the neutron-rich nucleus $^{38}$Mg as an example, the newly developed code is verified by the spherical relativistic continuum Hartree-Bogoliubov calculations, where only the spherical components of the densities are considered. When the deformation is included self-consistently, it is shown that the spherical components of density-dependent coupling strengths are dominant, while the contributions from low-order deformed components are not negligible.
