  We developed the self-consistent method for the calculation of the density of
states $N(\epsilon)$ in the SF bilayers. It based on the quasi-classical Usadel
equations and takes into account the suppression of superconductivity in the S
layer due to the proximity effect with the F metal, as well as existing
mechanisms of the spin dependent electron scattering. We demonstrate that the
increase of the spin orbit or spin flip electron scattering rates results in
completely different transformations of $N(\epsilon)$ at the free F layer
interface. The developed formalism has been applied for the interpretation of
the available experimental data.
