Ionisation de petites molecules par impact d’electrons : Etudes dynamique et de structure

Abstract

In this work, we studied by (e, 2e) experiment the dynamics of the ionization of small molecule of the XHn type (H2O, NH3, HF and CH4) and of the molecules of biological interest (the thymine) in the framework of the first and the second Born approximation. A single center basis has been used reducing the molecular problem to an atomic one. In the framework of the first Born , the overall agreement of the results of differential and total cross sections with the groups of the is reasonable for each molecule. In the second Born approximation, the first results of the ionization of the thymine will currently be of a good for under development by an Australien group.
