Abstract
The electric quadrupole moment Q for the ground state of 31Al (Iπ = 5/2+) was measured by means of the β ray-detected nuclear quadrupole resonance. A spin-polarized radioactive beam of 31Al was produced in the projectile-fragmentation reaction of a 40Ar beam on a 93Nb target. For the Q moment measurement, we developed a new radio-frequency application system to induce the spin reversal.
