Popis:	A noniterative integral equation approach to electron‐hydrogen atom scattering, including exchange, has been developed for the case in which all available channels are open. The technique has been implemented on a computer for the calculation of cross sections in the 1s–2s strong coupling exchange approximation and the 1s–2s–2p close coupling exchange approximation. The results of these calculations were found to be in good agreement with those obtained by the iterative solution of the differential equations. The merits of the noniterative integral equation technique are compared with other computational schemes for obtaining scattering information.
