The Schwinger variational principle has been applied to solve certain scattering problems in atomic physics, and a separable approximation has been used for the Hamiltonian of the bound subsystems. The (e<sup>+</sup>H) scattering length and the cross section for p(d mu <sup>-</sup>) elastic scattering has been calculated using the second Born approximation.
