Large-scale shell-model investigation of $2 I^½$ ECEC in $^{132}$ Ba and $^{78}$ Kr

Deepak Patel, Praveen C. Srivastava

We present a theoretical investigation of two-neutrino double electron capture ( $2 I^½$ ECEC) in $^{132}$ Ba and $^{78}$ Kr based on large-scale shell-model calculations. The nuclear ma…

Modification of single-hole-like states by configuration mixing in the $^{99 - 131}$ In

Deepak Patel, Praveen C. Srivastava, Noritaka Shimizu +1

Large-scale shell-model calculations are performed for the $9/ 2_{g.s.}^{+}$ , $1/ 2_{1}^{-}$ , $3/ 2_{1}^{-}$ , and $5/ 2_{1}^{-}$ states in the odd- $A$ indium isotopes with $N = 50 - 82$ . The calcula…
