Abstract Ionization channels of the molecular ion H2+ for various initial vibrational states in intense laser field (80 fs, 800 nm, I=6.8×1013 W/cm2) are theoretically investigated by numerically solving the time-dependent Schr?dinger equation. The results confirm that the channels largely depend on the selection of initial vibrational states by analyzing the variations of peak locations in the nuclear initial kinetic-energy-release spectra. Furthermore, the selection of the ionization channels is sensitive to the wavelength of the laser pulse. In addition, time-dependent competition between direct multi-photon ionization and charge-resonance-enhanced ionization are is discussed.
