Abstract
Computations were performed for calculating cross sections of electron impact scattering from astro-physical targets C<sub>a</sub>F, HCN and H<sub>2</sub>S at energies lower than their ionization potential. The results show that the use of highly accurate R-matrix method which includes all the relevant physics and chemistry of the molecule in its formalism generate features significantly different from the simple static exchange calculation. The data obtained shows interesting structures in the eigen-phase sums which may be attributed to the dissociation channel of the molecule.
