Low-energy neutrino responses for 71Ga by electron capture rates, charge exchange reactions and shell model calculations
Yoritaka Iwata, Hiroyasu Ejiri, Shahariar Sarkar
Weak Gamow-Teller (GT) responses for low-lying states in are crucial for studying low-energy solar neutrinos and the Ga anomaly, i.e., the possible transition…
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 Spin-Dependent Short-Range Correlations on Nuclear Matrix Elements for Neutrinoless Double Beta Decay of Ca
S. Sarkar, Y. Iwata
The 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…
Allowed decay of bare atoms with A 60-80 in stellar environments
Arkabrata Gupta, Chirashree Lahiri, S. Sarkar
We have calculated decay rates to the continuum and bound states of some fully ionized atoms in the stellar s-process environment having free electron density and temperature…
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…
