摘要：

Differential cross sections for the 2s-3s excitation of hydrogen atoms by electron and positron impact are reported at two incident energies, 10 eV and 50 eV, using a distorted wave method based on the two potential model. Dramatic differences between the electron and positron results are noticed at both energies.
