This series, established in 1965, is concerned with 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 put 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 inaccessible 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, their constituent parts and fields. Topics covered include related applied areas, such as atmospheric science, astrophysics, surface physics and laser physics.
