Electron-impact dissociation cross sections of vibrationally excited He2+ molecular ion

摘要

Electron-impact cross sections for the dissociation process of vibrationallyexcited He2+ molecular ion, as a function of the incident electron energy arecalculated for the dissociative transition X2\Sigma+u \to A2\Sigma+g by usingthe R-matrix method in the adiabatic-nuclei approximation. The potential energycurves for the involved electronic states and target properties, alsocalculated with the R-matrix method, were found to be in good agreement withthe results reported in literature.
