\textit{p} -壳层有效相互作用中张量力的修正

Modification of tensor force in \textit{p}-shell effective interaction

Kanhaiya Jha, Pawan Kumar, Shahariar Sarkar, P. K. Raina

摘要:

在许多壳模型相互作用中,张量力矩阵元经常保留源自裸张量力的系统趋势。然而,在本工作中,我们发现\textit{p} -壳层有效相互作用CK(8-16)的同位旋T = 0张量力矩阵元不具有这些系统性.我们通过用解析计算的张量力两体矩阵元修正CK(8-16)的T = 0张量力两体矩阵元来修正这些差异。通过对单粒子能量和TBME进行一些额外的修改,修正后的有效相互作用被命名为CKN。从激发谱、电磁矩、电磁和\textit{G}之间的低-\textit{T} eler(\textit{GT})跃迁等物理观点出发,对有效相互作用CKN进行了检验,计算了正常宇称态的\textit{p}壳核.所得结果令人满意。

英文摘要:

In many shell model interactions, the tensor force monopole matrix elements often retain systematic trends originating in the bare tensor force. However, in the present work, we find that Isospin T = 0 tensor force monopole matrix elements of \textit{p}-shell effective interaction CK(8-16) do not share these systematic. We correct these discrepancies by modifying T = 0 tensor force two-body matrix elements (TBMEs) of CK(8-16) by the analytically calculated tensor force TBMEs. With some additional modification of single-particle energies and TBMEs, the revised effective interaction is named as CKN. The effective interaction CKN has been tested for the calculations of \textit{p}-shell nuclei of normal parity states from various physics viewpoints such as excitation spectra, electromagnetic moments, and electromagnetic and \textit{G}amow-\textit{T}eller (\textit{GT}) transitions. The obtained results are found to be satisfactory.
