|Title:||Excitation Of The A1Πg And B3Π G Electronic States Of The Nitrogen Molecule By Electron Impact|
|Author:||Da Costa R.F.|
|Abstract:||Ab initio calculations were performed for the excitations of the a 1Πg and B3Πg and B 3Πg electronic states of the N2 molecule by impact of low-energy electrons. The scattering amplitudes were obtained by means of the Schwinger multichannel method within the scope of the minimal orbital basis for the single configuration interactions (MOB-SCI) approach. Through the use of the MOB-SCI strategy, we have investigated the coupling effects among ground state, first singlet, and first triplet excited states of the Πg symmetry. Integral and differential cross sections are shown for impact energies from near threshold up to 30 eV. Present results are compared with SMC two-state calculations and also with available theoretical and experimental data. © 2006 Wiley Periodicals, Inc.|
