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