The (n, p) reaction has been studied on the nuclei V and Co at an energy of 198 MeV. Spectra were measured at laboratory angles of 0, 4, 8', l2', 16', and 20' up to an excitation energy of 35 MeV in the Anal nuclei Ti and Fe. A multipole analysis of the data up to 30 MeV was carried out to identify Gamow-Teller (GT) (AL = 0, AJ = 1+) and spin-dipole (AL = 1, AJ = 0, 1,2 ) strengths. GT strength is concentrated in a resonance with centroid energy of 5.2 MeV in Ti and 4.1 MeV in Fe. The spin-dipole strength appears as a broad resonance with centroid energy about 16 MeV in both nuclei. Shell model calculations of the GT strength reproduce the energy distribution reasonably well, but the calculated strength exceeds the measurement by a factor of about 4.
