Schwinger's variational principle is used to evaluate excitation cross-sections of hydrogen atom by proton impact in a range of energies excluding a pertubative treatment. To describe the strong coupling between the excitation and the capture channels that exists at low energies, the continuum states have been introduced in the total wave function. Our results show that these states can describe properly the projectile capture states.
