Preface
This book is a collection of the contributions of most of the invited speakers to the International
Conference on "Electron and Photon Impact Ionization and Related Topics" which was held in
Louvain-la-Neuve, Belgium, from 1st to 3rd July 2004.
This meeting which takes place every year brought together about 80 scientists, from 19 different
countries, working in the field of simple and multiple ionisation by electron and photon impact
as well as related topics. The program included 22 invited talks and 54 posters on recent
experimental, theoretical and computational achievements in the realization, interpretation and
modelling of correlated processes involving a wide range of targets: atoms, molecules, clusters
or surfaces. Beside the regular talks, three review talks have been organized on three hot topics:
anisotropy and polarization in Auger-electron emission, multiple ionisation of atoms in strong
fields and theoretical and practical aspects of photo ionization with excitation.
Financial support from the "Faculte des Sciences de I'Universite catholique de Louvain" as well
as from the "Fonds National de la Recherche Scientifique de la Communaute Franc;aise de
Belgique" is gratefully acknowledged. This financial support permitted the participation of
young scientists from eastern and Latin American countries.
I thank the members of the International Scientific Committee and my colleagues, in particular
Xavier Urbain, as well as the students from the "Laboratoire de Physique atomique, moleculaire
et optique de l'Universite catholique de Louvain" for their help in the organization of this
meeting.
I am also indebted to Ugo Ancarani from the Universite de Metz who shared with me his
experience in organizing such meeting.
Finally, I want to thank all speakers who contributed to these proceedings and all participants
who gave their valuable time in carefully refereeing all contributions.
