La photoionisation d'ions présélectionnés en énergie cinétique. Une méthode basée sur la différence de potentiel retardateur appliquée à NO+ et O+ à partir de N2O.

摘要

A new method is described to obtain photoionization efficiency curves of kinetic energy-selected fragment ions. The method is tested and discussed in the case of the dissociative photoionization yields of NO+ and O+ from N2O. The attention is focussed on the dissociative autoionization processes in the threshold region, in the Franck-Condon region of the N2O(A2Sigma+) state and in the Franck-Condon gap between the A2Sigma+ and B2Pi states.
