Abstract :
Photoionization to the N2+ A 2Πu state is studied using photoelectron spectroscopy. Experimentally, vibrational branching ratios for the v′=0–3 levels obtained for the first time in the 20–34 eV region, show strong non Franck–Condon effects around 22 eV. Using ab initio many body perturbation theory, branching ratios for ionization to the A 2Πu state are calculated. This study indicates that the Franck–Condon breakdown in the photoionization of the N2 1πu electron is due to autoionization from Rydberg and valence states of N2.
