Abstract

Electric quadrupole coupling constant eqQ/h of the extremely proton-rich ²³Al (I^π = 5/2⁺, T_1/2 = 0.47 s) nucleus implanted into an Al₂O₃ 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 {pipe}eqQ/h(²³Al) {pipe} = 2.66±0.77 MHz. Using the quadrupole coupling constant of ²⁷Al in Al₂O₃ as a reference, the Q moment of the ground state of ²³Al was extracted as {pipe}Q(²³Al){pipe} ~ 160 mb, which is well explained by the shell model calculation in the sd-shell model space with the USD interaction.
