Magnetic Moment of the 80-keV1−State ofPr144

Abstract

The magnetic moment of the 80-keV ${1}^{\ensuremath{-}}$ state of $^{144}\mathrm{Pr}$ has been determined using the integral-reversed-field method of the perturbed angular correlations. The value of $\ensuremath{\mu}=(\ensuremath{-}4.3\ifmmode\pm\else\textpm\fi{}1.4){\ensuremath{\mu}}_{N}$ indicates a structure of the 80-keV level based on the mixing between two shell-model states, both having the odd neutron in ${f}_{\frac{7}{2}}$ configuration --- the odd proton occupying ${g}_{\frac{7}{2}}$ and ${d}_{\frac{5}{2}}$ configurations, respectively.
