Emission-energy distributions for cross sections as well as analyzing powers were investigated for (p-vector,{sup 3}He) reactions on {sup 59}Co and {sup 93}Nb to the continuum from a threshold of {approx}40 MeV up to the kinematic limit at incident energies of 130 and 160 MeV. A range of scattering angles from 15 degree sign to 140 deg. (laboratory) was explored. The experimental distributions were compared with a multistep direct theory in which a reaction mechanism based on deuteron pickup is employed. Reasonable agreement between experimental double differential cross sections and analyzing powers and the theoretical expectation was obtained. This work, together with published results for the same reaction and targets at a lower projectile energy of 100 MeV, allowed the incident-energy dependence of the cross section and analyzing power distributions to be explored.
