The ({ital {rvec p}},{ital n}) reaction has been measured for {sup 12}C and {sup 54}Fe targets at 290 MeV for a lab angle of 20.4{degree} and at 420 MeV for a lab angle of 24.0{degree}. An additional angle of 27.0{degree} was measured for {sup 12}C at 290 MeV. Both cross sections and analyzing powers were obtained up to excitation energies close to the quasifree peak. The ({ital {rvec p}},{ital n}) analyzing powers are suppressed relative to the free nucleon-nucleon values for the {sup 12}C data at 290 and 420 MeV, and for the {sup 54}Fe data at 290 MeV. An enhanced analyzing power is observed for the {sup 54}Fe data at 420 MeV. The data are compared with both relativistic and nonrelativistic model calculations.
