  The elastic and inelastic proton scattering on $^{18,20,22}$O nuclei are
studied in a folding model formalism of nucleon-nucleus optical potential and
inelastic form factor. The DDM3Y effective interaction is used and the ground
state densities are obtained in continuum Skyrme-HFB approach. A
semi-microscopic approach of collective form factors is done to extract the
deformation parameters from inelastic scattering analysis while the microscopic
approach uses the continuum QRPA form factors. Implications of the values of
the deformation parameters, neutron and proton transition moments for the
nuclei are discussed. The p-analyzing powers on $^{18,20,22}$O nuclei are also
predicted in the same framework.
