The papers in this work correspond to the invited talks at a conference dedicated to the study of all aspects of modern atomic physics. The meeting was designed both as a way of taking stock of what has been achieved and, it was hoped, as a means of stimulating new research, in new areas, along new lines. Consequently, an effort was made to touch on as many directions as possible. Amongst the topics included were: coincidence studies of atomic collisions, hollow atom, clusters, atom traps, Bose-Einstein condensates, atomic interferometry, density functional theory, atomic physics with anti-matter and surface adsorbates. The papers in this book covered a wide range of topics in modern atomic physics. These topics were chosen to reflect some of the main new directions in research. An effort was made to identify novel approaches and areas of study which hold out the maximal potential for further developments.

Topics covered in this book include electron scattering in the scanning TEM; basic theory of inelastic electron imaging; study of confined atoms by electron excitation; helium bubbles created in extreme pressure with application to nuclear safety; lithium ion implantation; electron and positron scattering from clusters; electron scattering from physi- and chemi-absorbed molecules on surfaces; coincidence studies; electron scattering from biological molecules; electron spectroscopy as a tool for environmental science; electron scattering in the presence of intense fields; electron scattering from astrophysical molecules; electron interactions and detection of x-ray radiation.

Revolutionary advances in experimental techniques and spectacular increases in computer power over recent years have enabled researchers to develop a much more profound understanding of the atomic few-body problem. One area of intense focus has been the study of fragmentation processes. Covering the latest research in the field, this edited text is the first to provide a focussed and systematic treatment of fragmentation processes, bringing together contributions from a range of leading experts. As well as tackling the more established electron-impact ionization processes, (e,2e), this book also guides the reader through topics such as molecular fragmentation, ion-atom collisions and multi-photon processes. Combining a broad range of topics with an equal mix of theoretical and experimental discussion, this is an invaluable text for graduate students and researchers in atomic collisions, laser physics and chemistry.

There is only a very limited number of physical systems that can be exactly described in terms of simple analytic functions.
