The electric quadrupole moment of the 33 13 Al 20 ground state, located at the border of the island of inversion, was obtained using continuous-beam β-detected nuclear quadrupole resonance (β-NQR). From the measured quadrupole coupling constant ν Q = 2.31(4) MHz in an α-Al 2 O 3 crystal, a precise value for the electric quadrupole moment is extracted: |Q s ( 33 Al)| = 141(3) mb. A comparison with large-scale shell model calculations shows that 33 Al has at least 50% intruder configurations in the ground state wave function, favoring the excitation of two neutrons across the N = 20 shell gap.33 Al therefore clearly marks the gradual transition north of the deformed Na and Mg nuclei towards the normal Z 14 isotopes.

“…The major part ∼(70 ± 13)% of the cross section is observed to populate the excited states of 32 Mg after the Coulomb breakup of 33 Mg. The shapes of the differential Coulomb dissociation cross sections in coincidence with different core excited states favor that the valence neutron occupies both the s 1/2 and p 3/2 orbitals.…”
