Elastic and inelastic scattering of 14.4-MeV protons from isotopically enriched targets of ^s.so'pi W ere studied. Angular distributions for many groups separated by more than 40 keV were obtained. The data were analyzed using the coupled-channel calculation. The vibrational collective model was used to describe the states of the bombarded nucleus. Several octupole states were found in both 46 Ti and 48 Ti but only one in 50 Ti. These results were compared with the results of a-particle scattering on the same nuclei. It was found that a discrepancy exists between the results of the experiments in the magnitudes of the deformabilities obtained for the octupole states. Spins and parities of some states in 48 Ti and 50 Ti were suggested. Electromagnetic transition rates were inferred from the deformabilities deduced from inelastic scattering data.
