Abstract

We report cross sections for electron-impact dissociative excitation of the B1Σu+, C1Πu, D1Πu, B1Σu+, and E,F1Σg+ singlet states of molecular hydrogen from all vi=014 vibrational levels of the ground X1Σg+ state. Calculations are performed using the adiabatic-nuclei convergent close-coupling method formulated in prolate spheroidal coordinates from threshold to 500 eV. Agreement with previous calculations varies with transition and impact energy, ranging from excellent to poor. Agreement with available experiment is generally good.
