Field-induced ion-pair formation in molecular hydrogen.

摘要: We present the first experimental results on electric-field dependence of threshold for ion-pair formation in a molecular system. The were obtained process ${\mathrm{H}}_{2}$+h\ensuremath{\nu}\ensuremath{\rightarrow}${\mathrm{H}}^{+}$+${\mathrm{H}}^{\mathrm{\ensuremath{-}}}$ by using double-resonance excitation scheme via E, $^{1}\mathrm{\ensuremath{\Sigma}}_{\mathrm{g}}^{+}$, v=6 level. similarity long-range interaction system with that electron-ion leads to analogies between field-induced and processes field ionization forced autoionization Rydberg states atoms.
