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.
Systematic study of the $α$ decay preformation factor of nuclei around the $\boldsymbol{Z=82}$, $\boldsymbol{N=126}$ shell closures within a generalized liquid drop model
本文基于广义液滴模型,系统地研究了152个核在$Z$ = 82,$N$ = 126封闭壳层附近的$α$衰变预形成因子$P_α$和$α$衰变半衰期,其中$P_α$是从计算的$α$衰变半衰期与实验值的比值中提取的。结果表明,$P_α$与价质子(空穴)$N_p$和价中子(空穴)$N_n$的乘积有明显的线性关系。同时,我们从Sun \textit{et al.} [\href {https://doi.org/10.1088/1361-6471/aac981}}{J. Phys. G:Nucl.Part. Phys. $\bm{45}$,075106(2018)}],其中$P_α$可以通过两个不同的显微公式计算。我们发现$P_α$也与$N_pN_n$有关。结合我们以前的工作[Sun \textit{et al.},\href {https://www.example.com PhysRevC.94.024338}{Phys. Rev.

Characterizing nuclear modification effects in high-energy O-O collisions at energies available at the CERN Large Hadron Collider: A transport model perspective
Off-the-energy-shell pp scattering in the exclusive proton knockout 12C(p,2p) reaction at 392 MeV
采用非相对论扭曲波脉冲近似(DWIA),精确处理了碰撞质子的运动学和质子-质子(pp)有效相互作用矩阵元的介质修正效应,研究了392 MeV下1 p ~(3/2)单粒子态~(12)C(p,2 p)质子敲除反应的三重微分截面(TDX).一些简化的近似在以前的研究与DWIA进行了检查。PP有效相互作用的能量壳层外矩阵元素在描述对应于动量传递固定的运动学的测量TDX的不对称两个峰中起着至关重要的作用。
