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…
