Περίληψη:	A variety of properties and processes in atomic, molecular and chemical physics can be conceptualized as being caused by nonstationary states satisfying state-specific complex eigenvalue Schrodinger equations (CESE). The imaginary part of the eigenvalue gives the rate of disintegration of the system. For ground or excited states dressed by an external dc- or ac-field, the energy shift is associated with linear and nonlinear polarizabilities. The CESE gives rise to all the conceptual and practical difficulties associated with the polyelectronic structures of excited states, as well as novel ones due to the presence of external fields and to the physical significance of the continuous spectrum. In a series of articles from this institute, it has been shown how advanced electronic structure theory and methods suitable for ground or excited states can be integrated in a practical way into selected elements of the rigorous theory of discrete states interacting with the continuous spectrum in order to solve the CESE nonperturbatively and efficiently and compute properties such as positions and partial widths of inner hole or multiply excited states, multiphoton ionization rates, multichannel predissociation lifetimes, nonlinear static and frequency-dependent polarizabilities, tunneling rates, magnetic field induced ionization of excited states and the Wannier problem of two-electron ionization near threshold. Here we outline this approach and present sample applications.
