Abstract

The first physics results measured using the TIARA array are reported. The reaction 24Ne(d,p)25Ne has been studied in inverse kinematics with a radioactive beam of 24Ne provided by SPIRAL at GANIL. TIARA is very compact with a high geometrical coverage for charged particles, and is designed specifically for the study of transfer reactions in inverse kinematics, with radioactive beams. From the (d,p) differential cross sections, the ground state of 25Ne is assigned to have Jπ = 1/2+ and the lowest states with Jπ = 5/2+ and 3/2+ are tentatively identified at excitation energies of 1.70 and 2.05 (±0.05) MeV, respectively. Coincident gamma-ray data proved essential to resolve these two excited states. Strongly populated levels observed at 3.30 and 4.05 (±0.05) MeV are candidates for negative parity states. Further analysis of the differential cross sections is in progress, with the aim of improving the identification of the higher lying states and determining absolute spectroscopic factors.
