Sažetak
The first direct experimental evidence of a multiparticle-hole ground state configuration of the neutron-rich 33Mg isotope has been obtained via intermediate energy (400 A MeV) Coulomb dissociation measurement.The major part∼(70±13)% of the cross section is observed to populate the excited states of 32Mg after the Coulomb breakup of 33Mg. The shapes of the differential Coulomb dissociation cross sections in coincidence with different core excited states favor that the valence neutron occupies both the s1/2 and p3/2 orbitals. These experimental findings suggest a significant reduction and merging of sd-pf shell gaps at N∼20 and 28.The ground state configuration of 33Mg is predominantly a combination of 32Mg (3.0, 3.5 MeV ; 2−, 1−) νs 1/2, 32Mg (2.5 MeV ; 2+) νp 3/2, and 32Mg (0 ; 0+) νp 3/2. The experimentally obtained quantitative spectroscopic information for the valence neutron occupation of the s- and p- orbitals, coupled with different core states, is in agreement with Monte Carlo shell model (MCSM) calculation using 3 MeV as the shell gap at N=20.
