Abstract

Preliminary results from the first application of the bi-orthogonal dilated electron propagator to the treatment of molecular resonances are presented for the energy and the width of the 2IIg shape resonance in e-N2 scattering. The corresponding resonant Feynman-Dyson amplitudes (FDAS) are plotted to get a quantitative affirmation of the topology of the lowest unoccupied molecular orbital (LUMO) for N2. It is shown that a plot of the resonant FDAS offer new insights into the role of correlation in the formation and decay of molecular shape resonances.
