The (p, d) and (p, t) reactions on /sup 18/O have been studied using the 24.4-MeV polarized proton beam of the Saclay cyclotron. Differential cross sections and analyzing powers (asymmetries) have been measured for eight deuteron and seven triton groups. These data are also compared with distorted-wave Born- approximation (DWBA) calculations as a list of their validity for a light nucleus. Some of the deuteron angular distributions are not accounted for by the calculations, and in fact for some transitions the results suggest that two-step processes might be involved. The reliablility of the spectroscopic information deduced from the (p, d) reaction is thoroughly discussed. In the triton optical potential a spin-orbit term with a well depth of about 4 MeV is necessary in order to fit the (p, t) analyzing power data for lhe transitions with L = 0 and L = 1. For higher angular momemtum re obtained only if a radial cutoff is used. The analysis of the transition to the 8.88-MeV (J/sup pi / = 2/sup -/) state in / sup 16/O indicates that the d state component in the triton wave function may be ates. (auth)
