Employing a coincidence three-dimensional momentum imaging technique, we investigate the ultrafast, intense laser-induced dissociation of a metastable NO2+ ion beam into N+ + O+. 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.
