Opis

Atomic and Molecular Beams covers the state of the art in this field both theoretically and experimentally. With many contributions from leading researchers, including several Nobel laureates, this book will serve as a long lasting source of reference on all aspects of fundamental research into or using atomic and molecular beams. The topics covered in this volume include amongst others laser cooling and manipulation of atoms and molecules, alignment, relaxation and condensation in supersonic jets, photodissociation, spectroscopy and state imaging in beams, dynamics of elementary molecular collisions, production and properties of clusters and nanoparticles and beam interactions with surfaces.
