摘要：

Five-state close-coupling equations for electron-helium scattering are solved in the energy region from 30 to 100 eV. Integral and differential cross sections for excitation of the ground state to the n=2 states 2S3, 2S1, 2P03, and 2P01 are presented. Calculated shapes of differential cross sections versus angle for various energies are in fair agreement with measurements, but the magnitudes of the cross sections are overestimated. Allowance for coupling between 2S3 and 2P03 brings calculated differential cross sections into good quantitative agreement with experiment. © 1979 The American Physical Society.
