Abstract
The photoelectron spectrum (PES) of the E 3Σ−u state of O2 has been measured with 3+1 multiphoton ionization (MPI). The observed vibrational progression in the PE spectrum is interpreted as due to ionization from a (3pπ)3Σ−u Rydberg state which is strongly mixed with the (πu 3π3g)B 3Σ− valence state. The observation of this mixing is in near agreement with the calculation by Buenker et al.Keywords
