The influence of initial vibrational states on ionization channels of the hydrogen molecular ion
Abstract:
The Coulomb explosion nuclear initial kinetic-energy-release spectra of the molecular ion H2+ for various initial vibrational states (from v=0 tov=7 ) are theoretically simulated by numerically solving the time-dependent Schrödinger equation in non Born-Oppenheimer approximation. The results confirm that ionization channels of H2+ contain direct multi-photon ionization, charge-resonance-enhanced ionization and charge-resonance-enhanced ionization with middle process. The ionization channels could be controlled by choosing different initial vibrational states.
