摘要：

The two-dimensional yield spectrum of fluorescence radiation from excited O atoms produced in the neutral photodissociation of O2 is measured as a function of both excitation photon wavelength of 50-62 nm (24.8-20 eV photon energy) and fluorescence wavelength of 80-140 nm. State-to-state neutral dissociation pathway of the Rydberg states converging onto O2+(c u-4), v′=1 into the O(ns S3)+O(D1) dissociation limit is revealed, where the principal quantum numbers of the Rydberg orbitals are conserved into those of excited O atoms. © 1995 The American Physical Society.
