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…
Nuclear matrix elements for mechanism of of Ca in nuclear shell-model: Closure versus nonclosure approach
Shahariar Sarkar, Y. Iwata, P. K. Raina
The and mechanisms of neutrinoless double beta decay () occur with light neutrino exchange via , and mediation, respectively. In the present s…
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…
