### Abstract

We report measurements of the cross section and a complete set of polarization transfer observables for the 16O(p-,n-)16F reaction at a bombarding energy of T_{p} = 296 MeV and a reaction angle of θ_{lab} = 0. 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} 8 MeV have been reasonably reproduced by the calculations except for the spin-parity Jπ = 2^{-} state at E _{x} = 5.86 MeV. The SD resonance at E_{x} 9.5 MeV appears to have more Jπ = 2^{-} strength than Jπ = 1^{-} strength, consistent with the calculations. The data show significant strength in the spin-longitudinal polarized cross section ID_{L}(0) at E_{x} 15 MeV, which indicates the existence of the Jπ = 0^{-} SD resonance as predicted in the SM calculations.

N2 - We report measurements of the cross section and a complete set of polarization transfer observables for the 16O(p-,n-)16F reaction at a bombarding energy of Tp = 296 MeV and a reaction angle of θlab = 0. 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 Ex 8 MeV have been reasonably reproduced by the calculations except for the spin-parity Jπ = 2- state at E x = 5.86 MeV. The SD resonance at Ex 9.5 MeV appears to have more Jπ = 2- strength than Jπ = 1- strength, consistent with the calculations. The data show significant strength in the spin-longitudinal polarized cross section IDL(0) at Ex 15 MeV, which indicates the existence of the Jπ = 0- SD resonance as predicted in the SM calculations.
