Electromagnetic Moments of $^{28}$P
ORAL
Abstract
In order to study nuclear structure of proton-rich nucleus $^{28}$P ($I^{\pi}$=3$^+$, $T_{1/2}$ = 270.3 ms), electro magnetic moments of this nucleus have been measured. Obtained precise value of magnetic moment is $|\mu(^{28}$P)$|$ = 0.3115(34) $\mu_N$. The experimental magnetic moment is much quenched from the Schmidt value +0.88, but is well reproduced by the shell model value +0.306. To measure quadrupole moment, $\beta$-NMR has been observed on $^{28}$P implanted in $\alpha$-Al$_2$O$_3$. As a preliminary result, possible resonance was found around quadrupole frequency $|\nu_Q|$ = 200 kHz, which corresponds to the quadrupole moment of about 120 mb, which is consistent with the shell model value.
