The {sup 16}O({ital n},{ital p}){sup 16}N reaction was measured at an incident neutron energy of 298 MeV at average center-of-mass angles of 2.0{degree}, 6.5{degree}, and 10.6{degree}. The Gamow-Teller (GT) and spin-dipole strength functions were extracted using a multipole decomposition technique with theoretical angular distributions with {ital L} transfers of 0, 1, and 2 from distorted-wave impulse-approximation (DWIA) calculations. The extracted strengths are compared to distributions expected from shell-model calculations which include 2{h bar}{omega} and 4{h bar}{omega} excitations. The pure spin-dipole multiplet at 0.2 MeV excitation shows a different shape than the angular distribution from the DWIA calculations, which may affect the amount of GT strength extracted from the multipole decomposition.
