摘要: We present ab initio time-dependent non-Hermitian Floquet calculations of multiphoton ionization (MPI) rates hydrogen molecular ions subject to an intense linearly polarized monochromatic laser field with a wavelength 800 nm. The orientation the axis is parallel polarization vector field. MPI are computed for wide range internuclear separations R high resolution in and reproduce resonance near-threshold structures. show that enhancement at critical related series higher electronic states. effect two-centre interference on signal discussed.
