Angle-resolved ion–electron coincidence experiments in molecular photoionization

Abstract

The development of angle-resolved photoion–electron coincidence experiments is shown in the example of the processes of dissociative photoionization and photodissociation with subsequent autoionization of molecular oxygen. The possibilities of double time-of-flight coincidence experimental setup installed on synchrotron are analysed. Examples of a data analysis of experimental multidimensional data arrays are presented. The procedure of multidimensional data transformation to an initial velocity–probability–angles array and several possibilities of data treatment, including three-dimensional representation, are discussed.
