Nuclear Level Density Determinations via 12C+27Al Proton Evaporation Spectra

Models for nuclear applications and nuclear astrophysics require nuclear reaction rates for a large number of reactions, though direct measurements are typically not possible. Instead, key nuclear properties are measured indirectly. For many nuclides, statistical properties are of interest, such as the nuclear level density and optical model potentials. We report preliminary results from 12C+27Al proton evaporation spectra measured at the Edwards Accelerator Laboratory, which we are analyzing with statistical model calculations to constrain the nuclear level density of 38Ar.
