Abstract

The mechanism of the enhanced ionization in H2 as a prototype of even-electron molecules was studied. It was found that the localized ionic configuration in the descending well is the main doorway state of ionization. In the large internuclear distance (R) region, the dynamics followed the covalent path. With the decrease of R, the population of H-H+ increased, whereas the ionization rate from a pure H-H+ decreased. As a result, the rate exhibited a peak at the critical distance Rc≈6 a.u..
