Abstract
The proton-capture reaction was studied via Coulomb dissociation (CD) of at an incident energy of about 500 MeV/u. The three lowest-lying resonances in have been populated and their resonance strengths have been measured. In addition, a nonresonant direct-capture component was clearly identified and its astrophysical factor measured. The experimental results are compared to Monte Carlo simulations of the CD process using a semiclassical model. Our thermonuclear reaction rates show good agreement with the rates from a recent compilation. With respect to the nuclear structure of we have found evidence for a negative-parity intruder state at 2.88-MeV excitation energy.
