Evidence for Increased neutron and proton excitations between 51-63Mn
Abstract
The hyperfine structures of the odd-even 51−63Mn atoms (N = 26 − 38) were measured using bunched
beam collinear laser spectroscopy at ISOLDE, CERN. The extracted spins and magnetic dipole moments
have been compared to large-scale shell-model calculations using different model spaces and effective
interactions. In the case of 61,63Mn, the results show the increasing importance of neutron excitations
across the N = 40 subshell closure, and of proton excitations across the Z = 28 shell gap. These
measurements provide the first direct proof that proton and neutron excitations across shell gaps are
playing an important role in the ground state wave functions of the neutron-rich Mn isotopes.
