E-Book Overview
This series, established in 1965, addresses recent developments in the general area of atomic, molecular, and optical physics. The field is in a state of rapid growth, as new experimental and theoretical techniques are brought to bear on many old and new problems. Such problems range from studies of the fundamental properties of radiation and matter, through studies of hitherto inaccesible states of "ordinary" and exotic atoms and molecules, the control of atoms and molecules by light, the behaviour of atoms and molecules in intense radiation fields, the detailed structure of such systems, including complex molecules and molecular clusters, and a wide range of interaction phenomena among atoms, molecules, and their constituent parts and fields. Topics covered also include related applied areas, such as atmospheric science, astrophysics, surface physics, and laser physics.
