Title: Electronic excitation of N-2 by positron impact

Abstract: We present cross sections of electronic excitation of nitrogen molecule (N-2) by positron impact using the Schwinger multichannel method. Our calculated cross sections are compared with the recent and the only available experimental data of Sullivan [Phys. Rev. Lett. 87, 073201 (2001)] . Present theoretical results for excitation to the a (1)Pi(g) states do not reproduce the near-threshold structure observed in the experimental data.
