Perturbed angular distributions with LaBr$_3$ detectors: the $g$ factor of the first ${10^+}$ state in $^{110}$Cd revisited

Abstract

The Time Differential Perturbed Angular Distribution technique with LaBr$_3$ detectors has been applied to the $I^\pi = \frac{11}{2}^-$ isomeric state ($E_x = 846$ keV, $\tau=107$~ns) in $^{107}$Cd, which was populated and recoil-implanted into a gadolinium host following the $^{98}$Mo($^{12}$C, $3n$)$^{107}$Cd reaction. The static hyperfine field strength of Cd recoil implanted into gadolinium was thus measured, together with the fraction of nuclei implanted into field-free sites, under similar conditions as pertained for a previous implantation perturbed angular distribution $g$-factor measurement on the $I^\pi = 10^+$ state in $^{110}$Cd. The $^{110}$Cd $g(10^+)$ value was thereby re-evaluated, bringing it into agreement with the value expected for a seniority-two $\nu h_{\frac{11}{2}}$ configuration.
