Abstract
The reaction was measured at the Holifield Radioactive Ion Beam Facility of the Oak Ridge National Laboratory to study the spectroscopy of the radionuclide . A 31-MeV proton beam from the 25 MV tandem accelerator bombarded isotopically enriched targets. Recoiling particles were identified by an annular silicon strip detector array. Two energy levels at and 7.132 MeV were observed for the first time. By comparing the experimentally obtained angular distributions and distorted wave Born approximation calculations, the spins and parities of energy levels were constrained. The astrophysically-important reaction rate was also calculated for the first time using resonance parameters for 12 energy levels.
