Abstract
Double-differential cross sections and spectra of analyzing powers, , for the reaction were measured at and at forward angles between and , and were analyzed using wave functions from the recoil-corrected continuum shell model (RCCSM). The steep rise of the cross-section spectra just above the rest energy threshold results from the excitation of the and resonances in and is well reproduced by the RCCSM at both incident energies. At higher excitation energies, the predicted cross sections fall off faster than the experimental values at forward angles. The absolute cross sections from the RCCSM were renormalized by factors of 1.3 and 1.6 at and , respectively, in order to fit the cross section summed over the lowest of excitation at the peak of the angular distribution. The , averaged over the lowest of excitation, are well reproduced by the RCCSM but not the , nor are the details of the spectra well described at either energy.
