Cross sections and analyzing powers for the [Formula Presented] reaction have been measured using a 150-MeV polarized proton beam from the AGOR cyclotron at KVI. For the stronger inelastic transitions, also spin-flip probabilities have been extracted. To predict cross sections and spin observables a microscopic (coordinate space) model of elastic scattering has been used, whereas for inelastic scattering calculations were performed in the distorted-wave approximation. In the model calculations a medium-modified two-nucleon effective interaction was used and nuclear structure information was obtained from shell-model calculations in a complete [Formula Presented] model space for parity-conserving transitions and a [Formula Presented] shell-model description in the case of parity-changing transitions. With the help of these model calculations, spin-isovector parts of the [Formula Presented] strengths for the negative-parity states at excitation energies of 2.125 MeV [Formula Presented] 4.445 MeV [Formula Presented] 5.020 MeV [Formula Presented] and 8.920 MeV [Formula Presented] have been extracted and compared to known Gamow-Teller strengths for the analog transitions to [Formula Presented].
