Based on the kinetic energy release and angular distributions, measured using both 774-nm and second-order-harmonic 387-nm pulses, we show that the main processes driving dissociation in pulses of about 1014W/cm2 peak intensity are one- and two-photon transitions from the X2Σ+ ground state to the A2Π first-excited state. First-order perturbation theory calculations also corroborate these findings.© American Physical Society (APS). This Item is protected by copyright and/or related rights.
