STUDY OF THE DIRECT (/cap alpha/, NUCLEON) REACTION, INCLUDING POLARIZATION
A theoretical study of the differential cross-section and nucleon polarization of the direct ( alpha , N) reaction at medium to high energies is carried out. An expression for the transition matrix element is derived from the distorted wave description, but only the distortion of the alpha -particle by the nucleus is taken into account in an illustrative calculation. It is argued that experimental studies of the polarization are useful for gaining insight into the reaction mechanism. This is explicitly demonstrated by including the spin- dependence and first order size effects of the interaction responsible for a knock-out process. The reaction examined has several advantages over the similar deuteron stripping process, one of which is the considerably high degree of the nucleon polarization. (auth)
