Structural evolution and K mixing in V49

Abstract

Lifetimes of a few negative parity levels and multipole mixing ratios ($\ensuremath{\delta}$) for a few dipole transitions in $^{49}\mathrm{V}$, populated through the $^{48}\mathrm{Ti}(^{4}\mathrm{He},2np)^{49}\mathrm{V}$ reaction with a 48 MeV $^{4}\mathrm{He}$ beam, were measured. The Indian National Gamma Array (INGA) facility was used to detect $\ensuremath{\gamma}$ rays at three different angles. Large basis shell model calculations were performed to understand the microscopic origin of these levels and to interpret the observations. $K$ mixing between different $K$ bands in $^{49}\mathrm{V}$ were established from one-nucleon-transfer spectroscopic factor calculations and total Routhian surface (TRS) calculations.
