Abstract

Electric quadrupole coupling constant eqQ/ h of the extremely proton-rich Al ( I = 5/2, T = 0.47 s) nucleus implanted into an AlO single crystal has been measured for the first time, using the β-ray detecting nuclear quadrupole resonance method ( β-NQR) in a high magnetic field. As a preliminary result, the quadrupole coupling constant was determined as | eqQ/ h(Al) | = 2.66±0.77 MHz. Using the quadrupole coupling constant of Al in AlO as a reference, the Q moment of the ground state of Al was extracted as | Q(Al)| ~ 160 mb, which is well explained by the shell model calculation in the sd-shell model space with the USD interaction.
