Abstract

Detector telescope measurements of cross sections and analyzing powers for the (p24,d) reaction to states of Mg23 up to 4.36 MeV in excitation are reported for bombarding energies of 49.2 and 150.3 MeV. Taken together with earlier spectrometer measurements at 94.8 MeV at the same laboratory, a smooth energy dependence of the results for transitions leading to 1/2+, 1/2, (3/2), (3/2)+, (5/2)+, and (7/2)+ states is obtained. Exact finite-range, adiabatic, distorted-wave analyses give reasonable fits in most cases to the cross-section angular distributions using an rms radius prescription for the bound-state geometry, and the energy-dependent set of proton optical potentials employed by Hatanaka extrapolated to higher energies; however, the calculated analyzing powers often differ in magnitude and shape from experiment. With the exception of the ln=0 transitions, spectroscopic factors derived from this particular comparison exhibit only a relatively small energy dependence.
