Cross sections at 0{degree} for the pure Fermi (0{sup +}, 2.31, MeV) and Gamow-Teller (1{sup +}, 3.95 MeV) states in the {sup 14}C({ital p},{ital n}){sup 14}N reaction have been measured at {ital E}{sub {ital p}}=494, 644, and 795 MeV using the LAMPF neutron time-of-flight facility with a new 617-m neutron flight path. The measured cross sections per unit transition strength, {cflx {sigma}}, provide a measure of the isovector spin-flip and non-spin-flip central components of the effective nucleon-nucleon interaction. Cross sections and the ratio {ital R}{sup 2}={cflx {sigma}}{sub GT}/{cflx {sigma}}{sub F} are compared to lower-energy measurements and to calculations using a free {ital NN} {ital t} matrix.
