The quasiparticle treatment of the electron-hydrogen problem performed in a recent publication is extended. It is shown that the characteristic polarization effect is essentially contained in the third-order quasi-Born approximation of the effective interaction, i.e., in an order which has not been considered in the aforementioned investigation. Instead of incorporating the corresponding contributions exactly, phenomenological polarization potentials proposed in the literature are used in the present calculations. With an adequate choice of the cutoff parameter in these expressions, almost perfect agreement between theory and experiment is achieved. The dependence on this parameter is studied. Comparison of our method with other procedures is being made.
