The general formalIsm of dIrect nuclear reactions at mtermedlate energIes IS developed on the assumptIOn that the reactIOn proceeds via a knock-out mechanIsm Takmg the example of an (a, N) reactIOn, where N stands for a spm ! partIcle whose structure can be neglected, calculatIOns are carned out m the dIstorted wave Born approxImatIOn The effects of the spm-dependent dIstortIOns m the mItral and final states appear m radIal wave functIOns and phase shIfts A finIte-range, spin-mdependent dIrect Interaction between a and N IS used ExplICIt formulas are obtaIned for the dIfferentIal cross sectIOn, tne,' polanzatIOn and the angular correlatIOn between the emItted partIcles and r-rays from subsequent decay of the final nucleus Several specIal cases are treated, such as S-state to S-state tranSItIons, and the sImplIficatIOns whIch occur for a zero-range dIrect interaction are conSIdered The applIcabIlIty of the present theory to vanous types of nuclear reactIOns IS dIscussed and ItS pOSSIble utIhty In studYIng the nuclear reactIon mechanIsm, the cluster structure of nucleI, and the nature of the nuclegr surface IS pomted out.

In Eq. (68a) the factor (-1)N/2 should be deleted. Therefore, the sum L +J has to be an even number for the scattering of identical nuclei.
