In the present work, spin-tensor decomposition method of two-nucleon interaction is employed to improve the discrepancy of T = 1 tensor force monopole matrix elements of the latest shell-model effective interaction of GX-family used for pf-shell nuclei. The single-particle energies of $0f_{7/2}$, $0f_{5/2}$, and $ 1p_{3/2}$ orbitals are also modified to reproduce the E($2^{+}_{1}$) of $^{48, 54}$Ca. The improved interaction is named as GX1R, and used to calculate the effective-single particle… Expand
