Within the boundary-corrected first Born approximation to the exact electron-transfer amplitude, a simple model is presented for representing the complex interactions between the projectile and the target nucleus plus nonactive electrons existing in an ion-atom collision. The one-electron Hartree-Fock density derived from the occupied orbitals is used. For proton-helium scattering comparison is made with the results obtained using strictly Coulomb potentials and with other screening results.
