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.
