The folding model for the nucleon-nucleus inelastic form factor is applied to study inelastic scattering of ^18,20O isotopes on proton target. A realistic density dependent M3Y interaction, well tested in the folding analysis of nucleus-nucleus scattering, is used as effective NN interaction. The nuclear ground state and transition densities (for the low-lying 2^+ and 3^- states in the oxygen isotopes) are obtained in the Hartree-Fock-BCS and generalized Bohr-Mottelson approach, respectively. Strong isovector mixing has been observed in the 2^+ inelastic channel of the ^20O+p system. The isovector strength of the form factor, implied by the inelastic ^20O+p data at ^43A MeV, gives a ratio of transition moments M^n_2^+ /M^p_2^+ ≃ 4.3 for the lowest 2^+ excitation in ^20O.
