Abstract: In this paper, we present a comparative study of low energy electron and positron scattering by H2 and N2 molecules, using the Schwinger multichannel (SMC) method. We briefly discuss the elastic collision of electrons and positrons by H2 below positronium formation threshold. The electronic excitation of N2 by electron impact is then compared with available data in the literature and with previously published results by positron impact. Strategies to treat the nuclear dynamics in the collision process, specifically adiabatic approximation for direct scattering and boomerang model for resonant scattering, are introduced within the SMC context. Partial results for H2 are shown. © 2006 Elsevier B.V. All rights reserved.
