论文摘要

将核子对壳模型(NPSM)施加到所谓的M-SCHEME中,以进行同义对称性和没有同胞对称性的情况。奇数系统甚至系统都在同一脚上进行处理。给出了适用于M-Scheme的核子对的未耦合换向器。获得了重叠的M-Scheme矩阵元素的显式公式,一体操作员,两体操作员。发现用于计算M-Scheme中矩阵元素的$ CPU $时间比NPSM的J-Scheme中的时间要短得多。

The nucleon pair shell model (NPSM) is casted into the so-called M-scheme for the cases with isospin symmetry and without isospin symmetry. The odd system and even system are treated on the same foot. The uncoupled commutators for nucleon-pairs, which are suitable for M-scheme, are given. Explicit formula of matrix elements in M-scheme for overlap, one-body operators, two-body operators are obtained. It is found that the $cpu$ time used in calculating the matrix elements in M-scheme is much shorter than that in the J-scheme of NPSM.
