Abstract
The $^{16}\mathrm{O}$(n,p${)}^{16}$N reaction was measured at an incident neutron energy of 298 MeV at average center-of-mass angles of 2.0\ifmmode^\circ\else\textdegree\fi{}, 6.5\ifmmode^\circ\else\textdegree\fi{}, and 10.6\ifmmode^\circ\else\textdegree\fi{}. The Gamow-Teller (GT) and spin-dipole strength functions were extracted using a multipole decomposition technique with theoretical angular distributions with 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\ensuremath{\Elzxh}\ensuremath{\omega} and 4\ensuremath{\Elzxh}\ensuremath{\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.
