Ground-state magnetic-dipole moment of $^{37}$Ca*

ORAL

Abstract

The ground-state magnetic-dipole moment of $^{37}$Ca, which has one neutron add to $^{36}$Ca with the neutron number $N$ = 16, was determined to probe the closed-shell nature of the $^{36}$Ca nucleus. The hyperfine spectrum of the D2 transition in $^{37}$Ca ion was measured using collinear laser spectroscopy technique at BECOLA at NSCL/MSU. The resulting magnetic moment was compared with the shell model and in-medium similarity renormalization group calculations. The details of experiment and results will be discussed.
