The first measurements of {ital D}{sub {ital NN}}(0{degree}) for ({ital {rvec p}},{ital {rvec n}}) reactions at 295 MeV yield large negative values up to 50 MeV excitation for the {sup 6}Li,{sup 11}B,{sup 12}C, {sup 13}C({ital {rvec p}},{ital {rvec n}}) reactions, suggesting much stronger spin-flip strength than observed at lower bombarding energies. DWIA calculations using the Franey and Love (FL) 270 MeV interaction reproduce differential cross sections and {ital D}{sub {ital NN}}(0{degree}) values, while the FL 325 MeV interaction yield {ital D}{sub {ital NN}}(0{degree}) values less negative than the experimental values, suggesting that its exchange tensor part is too strong at large momentum transfer ({ital Q}{congruent}3.4 fm{sup {minus}1}).
