Special features of the alpha induced d and polarized d breakup
The alpha induced deuteron breakup reactions have been of interest since the three-nucleon, nucleon induced deuteron breakup, problem was addressed with tractable and predictive codes based on the Faddeev formalism and with appropriate nucleon-nucleon forces. In this paper we discuss a few special features of the alpha induced deuteron breakup reactions. Specifically, we point out the importance of the n-p tensor force in the predictions of the three-body model that fit the tensor analyzing powers better and the concommittent deterioration of the fit to the vector analyzing power caused by the inclusion of the tensor force. We suggest that there exists evidence for the /sup 1/S/sub 0/ n-p interaction, which is isospin forbidden, in both the cross section and spin observables data. Finally, we discuss certain characteristics of the p-..cap alpha.. quasifree-scattering and n-..cap alpha.. final-state-interaction processes.
