Description
The (n,p) reaction has been studied on the nuclei 51V and 59Co at an energy of 198 MeV. Spectra were measured at laboratory angles of 0 degree, 4 degree, 8 degree, 12 degree, 16 degree, and 20 degree up to an excitation energy of 35 MeV in the final nuclei 51Ti and 59Fe. A multipole analysis of the data up to 30 MeV was carried out to identify Gamow-Teller (ΔL=0,ΔJπ=1+) and spin dipole (ΔL=1,ΔJπ=0-,1-,2-) strengths. GT strength is concentrated in a resonance with centroid energy of 5.2 MeV in 51Ti and 4.1 MeV in 59Fe. 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 four
