Nuclear forces and nuclear excited states
Pawan Kumar, Kanhaiya Jha
In this work, the role of the central, spin-force and tensor forces of two-nucleon interaction in building the first 2 and 4 states of 20 sd-shell nuclei is studied. Calcul…
Nuclear matrix elements calculation for decay of Sn using nonclosure approach in nuclear shell model
Shahariar Sarkar, P. K. Rath, V. Nanal +5
In this study, we calculate the nuclear matrix elements (NMEs) for the light neutrino-exchange mechanism of neutrinoless double beta ) decay of Sn within the framewor…
Effect of tensor force on lowering of 5/2 level in heavier Cu isotopes
Kanhaiya Jha, P. K. Raina
The inversion of 3/2 and 5/2 levels in heavier Cu isotopes is one of the most visible example of shell-evolution, caused by the strong monopole attraction between the n…
Modification of tensor force in \textit{p}-shell effective interaction
Kanhaiya Jha, Pawan Kumar, Shahariar Sarkar +1
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 fi…
Role of individual components of two-nucleon interaction in nuclear matrix elements of and of Ca: Beyond the closure approximation
Shahariar Sarkar, Pawan Kumar, Kanhaiya Jha +1
In the present work, we examine the role of central (C), spin-orbit (SO) and tensor (T) components of two-nucleon interaction in the nuclear matrix elements (NMEs) of the two-neutr…
A way forward towards improvement of tensor force in \textit{pf}-shell
Kanhaiya Jha, Pawan Kumar, Shahariar Sarkar +2
In many shell model interactions, the tensor force monopole matrix elements often retain systematic trends originating in the bare tensor force. In this work, however, we note for…
