This volume presents and reviews trends and developments in the following active areas of research in atomic and molecular physics: Structure and properties of clusters: atomic dynamics in intense laser fields, (e, 2e) and photoionization processes, electron impact total ionization from atoms and molecules, electron excitation of autoionizing atoms and depopulation of Rydberg atoms, Quantum optical resonances; multiphoton and multistep laser ionization spectroscopy and life time measurement of NO2.

Contemporary research in atomic and molecular physics concerns itself with studies of interactions of electron, positron, photons, and ions with atoms, molecules, and clusters; interactions of intense ultrashort laser interaction with atoms, molecules, and solids; laser assisted atomic collisions, optical, and magnetic traps of neutral atoms to produce ultracold and dense samples; high resolution atomic spectroscopy and experiments by using synchrotron radiation sources and ion storage rings. In recent years, important advances have been made in the experimental as well as theoretical...
