The ( d,3He)-reactions on the target nuclei48,50Ti and51V have been studied with 52 MeV deuterons. The data were analyzed by means of the DWBA which is shown to be applicable at this energy. All our results agree well with the assumption of pure ( f 7/2)n proton configurations for these nuclei. The inelastic scattering of 52 MeV deuterons from the lowest 2+ state in48Ti has been described in terms of the collective model as well as of the microscopic shell model. Good fits to the measured angular distributions have been obtained with reasonable values for the deformation parameters and the basic nucleon-nucleon interaction.
