Study of bound and resonant states of NS molecule in the R-matrix approach

Abstract The bound and resonance states along with corresponding autoionization widths for nitrogen sulphide (NS) molecule are determined using electron NS + cation scattering calculations. calculations performed 2 Σ , Π Δ total symmetries the ab initio R -matrix method both continuum states. Calculations on a grid of 106 points internuclear separations between 1.32 3 Å. yield dissociative potential curves which, when considered together their widths, provide input models different electron-cation collision processes including recombination (DR), rotational vibrational excitation. Curves couplings which will lead directly to DR identified.
