论文摘要
碳同位素的基态特性，包括根平方半径，中子分离能，单个粒子光谱和形状，在连续体中使用变形的相对论Hartree-Bogoliubov理论系统地研究了。有效交互的计算PK1可以很好地重现可用数据。该同位素链中的壳演化是通过检查单个粒子光谱来研究的。中子轨道$ν2S_{1/2} $和$ν1D_{5/2} $的反转与稳定核中的中子轨道的顺序相比，在$^{15-20,22} \ m athrm {c}中以这些核约束在螺旋形的形状上。详细研究了$^{15,19,22} $ C中的中子光环，其光环结构主要是由（$ν2S_{1/2}，ν1D_{5/2} $）的反转引起的。特别是，$^{15} $ c和$^{22} $ c是变形的晕核核，在基态中具有形状脱钩效果。
Ground state properties of carbon isotopes, including root-mean-square radii, neutron separation energies, single particle spectra, and shapes are systematically studied with the deformed relativistic Hartree-Bogoliubov theory in continuum. The calculations with the effective interaction PK1 reproduce the available data reasonably well. The shell evolution in this isotopic chain is investigated by examining the single particle spectra. The inversion of neutron orbitals $ν2s_{1/2}$ and $ν1d_{5/2}$ compared with the order of neutron orbitals in stable nuclei is revealed in $^{15-20,22}\mathrm{C}$ when these nuclei are constrained to spherical shape. Neutron halos in $^{15,19,22}$C are studied in detail and their halo structures are mainly caused by the inversion of ($ν2s_{1/2},ν1d_{5/2}$) and deformation effects. In particular, $^{15}$C and $^{22}$C are deformed halo nuclei with shape decoupling effects in ground states.
