摘　　要：Ionization channels of the molecular ion H^(+)_(2) for various initial vibrational states in intense laser field(80 fs,800 nm,I=6.8×10^(13) W/cm^(2))are theoretically investigated by numerically solving the time-dependent Schrödinger 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.
