摘要：

The R-matrix method has been used to study the scattering of electrons by oxygen molecules for impact energies in the range from threshold to 1 5 eV. Electronic excitation cross sections for transitions to the a1-DELTA(g), b1-SIGMA(g)+, and "6 eV" states of oxygen are presented. Important contributions from a 2-PI(u) resonance, in addition to the well-known 2-PI(g) resonance, are found to significantly modify previous theoretical predictions. Integral elastic scattering cross sections are also obtained for the first time for a complicated open-shell system using an ab initio method.
