N2 - The ground-state electric quadrupole moment of Al31(Iπ=5/2+,T1/2=644(25) ms) has been measured by means of β-ray-detected nuclear magnetic resonance spectroscopy using a spin-polarized Al31 beam produced in the projectile fragmentation reaction. The obtained Q moment, |Qexp(Al31)|=112(32)emb, is in agreement with conventional shell model calculations within the sd valence space. Previous results on the magnetic moment also support the validity of the sd model in this isotope, and thus it is concluded that Al31 is located outside of the island of inversion.
