| 英文摘要 | Nuclear deformations are fundamentally important in nuclear physics. We recently developed a multidimensionally constrained relativistic Hartree-Bogoliubov (MDCRHB) model, in which all multipole deformations respecting the V (4) symmetry can be considered self-consistently. In this work we extend this model by incorporating the angular momentum projection and parity projection to restore the rotational and parity symmetries broken in the mean-field level. This projected MDCRHB (p-MDCRHB) model enables us to connect certain nuclear spectra to exotic intrinsic shapes such as triangles or tetrahedrons. We present the details of the method and an exemplary calculation for C-12. We develop a triangular moment constraint to generate the triangular configurations consisting of three alpha clusters arranged as an equilateral triangle. The resulting C-12 spectra are consistent with that from a triangular rigid rotor for large separations between the alpha clusters. We also calculate the B(E2) and B(E3) values for low-lying states and find good agreement with the experiments. |
