  We report measurements of the cross section and a complete set of
polarization transfer observables for the ${}^{16}{\rm
O}(\vec{p},\vec{n}){}^{16}{\rm F}$ reaction at a bombarding energy of $T_p$ =
296 MeV and a reaction angle of $\theta_{\rm lab}$ = $0^{\circ}$.
  The data are compared with distorted-wave impulse approximation calculations
employing the large configuration-space shell-model (SM) wave functions.
  The well-known Gamow-Teller and spin-dipole (SD) states at excitation
energies of $E_x$ $\lesssim$ 8 MeV have been reasonably reproduced by the
calculations except for the spin--parity $J^{\pi}$ = $2^-$ state at $E_x$ =
5.86 MeV.
  The SD resonance at $E_x$ $\simeq$ 9.5 MeV appears to have more $J^{\pi}$ =
$2^-$ strength than $J^{\pi}$ = $1^-$ strength, consistent with the
calculations.
  The data show significant strength in the spin-longitudinal polarized cross
section $ID_L(0^{\circ})$ at $E_x$ $\simeq$ 15 MeV, which indicates existence
of the $J^{\pi}$ = $0^-$ SD resonance as predicted in the SM calculations.
