Magnetic moment of $^{23}$Ne

ORAL

Abstract

The magnetic moment of the \textit{$\beta $}-emitting nucleus $^{23}$Ne ($I^{\pi }$ = 5/2$^{+}$, $T_{1/2}$ = 37.2 s) has been remeasured by means of the \textit{$\beta $}-NMR method. The $^{23}$Ne nuclei were produced in the single neutron pickup and the projectile fragmentation processes using 100$A$-MeV $^{22}$Ne and $^{26}$Mg beams, respectively, impinged on a Be target at NIRS-HIMAC, and were separated by the fragment separator. After selection of the reaction angle and the momentum to obtain polarization, the $^{23}$Ne nuclei were implanted into a NaF single crystal at 15 K. The magnitude of polarization of $\sim $3{\%} for $^{23}$Ne in NaF obtained in the pickup process was much larger than that in the fragmentation process. From the NMR spectra, we obtained the magnetic moment $\vert $\textit{$\mu $}($^{23}$Ne)$\vert _{uncorrected}$ = (1.081 $\pm $ 0.001)\textit{$\mu $}$_{N}$ as the preliminary result.
