Abstract

The level structure of Na22 has been studied at the Holifield Radioactive Ion Beam Facility in Oak Ridge National Laboratory using the Mg24(p,He3)Na22 reaction. Proton beams of 41 and 41.5 MeV were generated by the 25-MV tandem accelerator and bombarded isotopically enriched Mg24 targets. Angular distributions of recoiling He3 particles were extracted by using a segmented annular silicon strip detector array. Spins and parities for 10 levels were constrained through a distorted-wave Born approximation analysis of angular distributions, including three levels above the proton threshold at 6.739 MeV.
