Abstract: The nuclear electric quadrupole moment (Q moment) of the neutron-rich nucleus Al-33 (I = 5/2, T-1/2 = 41 ms) has been measured by the beta-ray detected nuclear quadrupole resonance (beta-NQR) method for the first time. The Al-33 nucleus is considered to be on the border of the island of inversion within which a significant intrusion of the pf orbits occurs across the N = 20 shell gap and the intrusion causes an anomalous enhancement of the Q moment. Polarized Al-33 nuclei were produced from S-36 (77.5MeV/u) beams through the fragmentation process and separated by LISE fragment separator at GANIL. The Al-33 nuclei were implanted into a Al2O3 single-crystal plate and the beta-NQR spectrum was successfully obtained.
