    A way forward towards the improvement of tensor force in pf-shell
    (Elsevier, 2020) Jha, Kanhaiya; Kumar, Pawan; Sarkar, Shahariar; Raina, P. K.; Aydin, Sezgin
    In many shell model interactions, the tensor force monopole matrix elements are observed to retain sys-tematic trends originating in the bare tensor force. In this work, however, we note for GX-interactions of pf-shell that the seven out of ten T = 1 tensor force monopole matrix elements do not share these systematic. We ameliorate this disparity making use of Yukawa-type tensor force and spin-tensor decomposition. Furthermore, we have modified the single-particle energy of 1(p3/2) orbit and two TBMEs of 0f-orbit, and the revised interaction has been tested from Ca to Ge isotopes with various physics viewpoints. The results are found to be satisfactory with respect to the experimental data. (c) 2020 Elsevier B.V. All rights reserved.
