Abstract
A multichannel eikonal treatment of atomic collisions is presented and applied to the excitation of atomic helium by electrons with incident energy in the range eV. Two different sets of orthogonal wave functions are employed. A four-channel description yields differential- and total- excitation cross sections in satisfactory agreement with experiment.
