Shape coexistence in the "Island of inversion": Search for the 02+ state in 32Mg applying a two-neutron transfer reaction — •Kathrin Wimmer, Vinzenz Bildstein, Roman Gernhäuser, Thorsten Kröll, and Reiner Krücken — Physik-Department E12, Technische Universität München

The "Island of inversion" is a region in the nuclear chart around the neutron rich N=20 isotopes of Na, Mg and Al isotopes, where intruder fp-orbitals favoring deformed shapes compete with the normal spherical sd configurations. The two-neutron transfer reaction starting from the normal ground state of 30Mg is expected to favor the population of its analogue in 32Mg, the excited 02+ state which has a similar particle-hole structure. This state is practically not reachable in Coulomb excitation and its population has neither been observed in the β decay of 32Na nor in heavy-ion induced reactions. We populated states in 32Mg by a (t,p) two-neutron transfer reaction in inverse kinematics with a 30Mg beam at 1.83 MeV/u from REX-ISOLDE impinging on a tritium-loaded Ti target. Recoiling light particles, like protons and tritons, were detected in the new segmented Silicon detector array especially designed for transfer reactions surrounded by the MINIBALL γ-ray detector.
First results of this beam time which took place in October 2008 will be presented.
