Abstract
The folding model for the nucleon-nucleus inelastic form factor is applied to study inelastic scattering of 1 8 , 2 0 O 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 2 0 O+p system. The isovector strength of the form factor, implied by the inelastic 2 0 O+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 2 0 O.
