ANALYZING POWER FORMULAS FOR NUCLEAR-REACTIONS IN THE LOW-ENERGY LIMIT AND APPLICATIONS TO THE H-2((D)OVER-RIGHT-ARROW, P)H-3, HE-3((D)OVER-RIGHT-ARROW, GAMMA)LI-5 AND LI-7((P)OVER-RIGHT-ARROW, GAMMA)BE-8 REACTIONS

For nuclear reactions to two-body final states, simple formulae of ana lyzing powers for polarized beams are derived in a model-independent w ay, when spin-dependent interactions are weak. The formulae are applic able to reactions at extremely low incident energies to a large extent , as far as the parity is conserved. For example, measured cross secti ons and analyzing powers in the H-2((d) over right arrow p)H-3 reactio n at E(d) = 30-90 keV, the He-3 ((d) over right arrow,gamma)Li-5 react ion at E(d) = 800 keV and the Li-7((d) over right arrow gamma)Be-8 rea ction at E(p) = 0-80 keV are analyzed by the formulae with successful agreements between the data and the formulae. The analyses provide val uable information on the mechanisms of these reactions.
