摘要: We report the observation and characterization of a new nonresonant strong field ionization mechanism in polyatomic molecules: Nonadiabatic multi-electron (NME) dynamics. The response given molecule depends on important properties such as molecular geometry bonding, path length delocalized electrons and/or potential well basic laser pulse parameters wavelength intensity. Popular quasi-static tunnelling models ionization, based upon adiabatic single active electron, are demonstrated to be inadequate when electron delocalization is important. NME greatly affects its fragmentation energetics. In addition, effects shown present even long limit.
