Exactly soluble multichannel scattering problems with Coulomb interactions

A general separable potential approach to elastic and inelastic scattering processes is developed which takes account of Coulomb interactions in an exact way. Effective nuclear interactions are used that are separable in the channel relative motion variables and take explicit account of the coupled-channel nature of the problem. After solving the coupled-channel integral equations by means of both matrix inversion techniques and a suitable channel-decoupling procedure, we arrive at exact manageable expressions of the Coulomb-corrected nuclear transition amplitudes.
