Neutral fragmentation of super excited oxygen molecules
(2000) In Physical Review A (Atomic, Molecular and Optical Physics) 61(3).- Abstract
- The mechanisms of neutral dissociation of oxygen molecules in the excitation energy range 15–25 eV have been studied in a dispersed fluorescence experiment. By detecting the fluorescence from excited oxygen atoms, we find that neutral superexcited O2 states below 20 eV dissociate into O(g.s.)+O(3s,3p). At higher excitation energies (hν=20–25 eV) the curve-crossing interactions following excitations to members of the Rydberg c 4Σu- series also yield atoms in Rydberg states (nl,n>~4). The experimental data are analyzed on the ground of many-body perturbation theory, calculations which indicate the structure of the predissociating states converging to the experimentally observed ones.
