“…The theoretical wave function configurations having a neutron with orbital angular momentum l = 0, 2, obtained using the calculated USDB single-particle energies, and the associated cross sections are also shown for comparison. Some discrepancies between the theoretical and experimental energy spectra of 32 Al are present at low excitation energy, similar to those pointed out in Ref. [32].…”

“…At N = 20 and Z = 11, 12 the experimental g factors were already found to deviate strongly from the sd shell model predictions. Particle-hole excitations recognized as intruder states have been also found in excited states of 32 Al at around 1 MeV and of 33 Al at 730 keV [13,14]. Thus, a possible extension of a deformed region beyond Z = 12 has been considered.…”

“…As a consequence, the energy of the 2p 3/2 orbital was decreased by 0.5 MeV with respect to the original spdf orbital. Recently, the discovery of the shape coexisting 0 + state in 32 Mg at 1058 keV by a two-neutron transfer reaction has underlined how the SDPF-M effective interaction underestimates the p 3/2 component in the 32 Mg ground-state wave function [19]. Only β-decay studies have been done at Z = 13 and N = 22, 23.…”

“…In order to study the single-particle mixing for N = 20 to 22 in the Al isotopes, we measured the longitudinal momentum distributions of the 32,33,34,35 Al fragments from one-neutron removal reactions at around 900 MeV/u and the corresponding cross sections. The momentum distribution analysis has been performed in the eikonal framework.…”

The one-neutron removal cross sections of neutron-rich Al isotopes and longitudinal momentum distributions of the residues have been measured for A = 33 to 36 at relativistic energies (≈900 MeV/u). The inclusive data have been interpreted within the eikonal approximation. The evolution of the single-particle occupancy in the ground state of 33,34,35 Al has been studied and compared with shell model predictions. The inferred 2s 1/2 neutron occupancy in the 33 Al ground-state wave function is 20% to 40% lower than the predicted one. The inclusive data do not exclude the presence of intruder states. Some intruder l = 1 occupancy is found in 34 Al, similarly to 33 Mg. The single-particle 1f 7/2 occupancy shows a gradual increase at N = 22. Correspondingly, a decrease of the 1d 3/2 strength has been observed.
