Abstract

The g-factor of the extremely proton-rich nucleus 23Al (T1/2 = 0.47 s) has been measured by means of the β-NMR method for the first time. The g-factor were determined as |g| = 1.557(88) from the obtained NMR spectra. From the comparison between the experimental value and the shell model calculation, the spin parity of the ground state of 23Al was determined as Iπ = 5/2+. Thus, the magnetic moment of 23Al was determined as |μ| = 3.89(22)μN.

Abstract

The electric quadrupole coupling constant eqQ/h of 25Na (Iπ = 5/2+, T1/2 = 59.6 s), implanted in a TiO2 single crystal, has been measured by use of the β-NMR technique, to determine the electric quadrupole moment Q. As a result, |eqQ/h| = (44 ± 16) kHz and |Q(25Na)| = (1.0 ± 0.4) mb were determined. From the NMR on 25Na in NaCl, the magnetic moment was determined as |µ| = (3.6832 ± 0.0003) µN
