Neutrinoless double beta decay is a pivotal weak nuclear process that holds the potential to unveil the Majorana nature of neutrinos and predict their absolute masses. In this study, we delve into examining the impact of spin-dependent short-range co

In the present work, the λ mechanism (left-right weak boson exchange) and the light neutrino-exchange mechanism of neutrinoless double beta decay is studied. In particular, much attention is paid to the calculation of nuclear matrix elements for one

In the present work, we examine the sensitivity of nuclear matrix elements (NMEs) for light neutrino-exchange mechanism of neutrinoless double beta decay ($0\ensuremath{\nu}\ensuremath{\beta}\ensuremath{\beta}$) of $^{48}\mathrm{Ca}$ to the central,

In the present work, the effect of proton-neutron interaction and its different components, i.e., central, spin-orbit, and tensor force, on proton shell-structure of odd-$A$ Sc, F, and Li isotopes is studied within the nuclear shell model framework.

The spin-tensor decomposition is employed to construct a new interaction, named CKHeN, for 0p-shell. This new interaction is used to calculate the ekective single-particle energies of π0p1/2 and π0p1/2orbitals in Li isotopes, and the level structur

In many shell model interactions, the tensor force monopole matrix elements are observed to retain systematic 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

We examine the sensitivity of nuclear matrix elements (NMEs) for light-neutrino exchange mechanism of neutrinoless double beta decay (0νββ) for 48Ca to the various components of two-nucleon interaction, GXPF1A, in fp model space. It is found that
