Probing Molecules with Slow Electrons and Positrons Impacting on Gaseous Targets F.A. Gianturco Department of Chemistry, The University of Rome “La
Sapienza” and INFM, Electron beams have been used over the years for the study of a very broad variety of molecular properties, ranging from the fundamental study of low-energy resonances, electron-induced molecular fragmentation, excitation, dissociative attachment and recombination to the analysis of plasma production by electrons and of chemical vapour deposition initiated by electron impact [1]. Likewise, positrons have been widely used both for probing gas properties at the molecular level [2] and for their use in several applied field related, for example, to defects in solids and to polymer formation [3]. In the present talk I shall endeavour to show that the theoretical
understanding of such processes and the computational modelling of the
relevant observables has also made good progress in recent years and that we
are now able to gather a great deal of data which pertain to simple systems
and also to analyse with good reliability the behaviour of complex gases
like fullerenes or biomolecular targets [4,5]. References |
