Abstract
The comparison of the kinetic energy distribution of C2+ ionic fragments produced from CO2 by subpicosecond multiquantum ionization at an intensity of ~ 2 × 1017 W/cm2 with the corresponding distributions arising from ion/molecule collisions and Auger processes reveals an important common feature of the collisional, Auger, and multiphoton interactions. The principal finding is a marked similarity in the production of anomalously energetic C2+ ions arising from high-lying CO2+ precursors having a substantial charge-transfer character, an outcome that echoes related results observed in N2. These results suggest that charge-transfer states may play a generally significant role in multiphoton couplings for broad classes of molecular materials.
