d−γAngular Correlations as a Test for the Importance of Multistep Processes in the ReactionMg24(d, d′)

The in-plane ${}_{}{}^{24}{}_{}{}^{}\mathrm{Mg}(d, d_1\gamma )$ angular correlation has been measured at an incident energy of 10 MeV. Analyses of the experimental data with distorted-wave and coupled-channel Born-approximation calculations show that multistep processes are important to describe this reaction although the distorted-wave Born approximation reproduces quite well the differential cross section.
