内容简介：
This survey of perspectives, techniques and results in quantum theory contains 26 chapters by leading quantum chemists and physicists drawn from 14 countries. The book covers a wide range of topics, though the emphasis throughout is on new approaches and their interrelationships. Topics covered include dimensional scaling, the hyperspherical method applied both to reactive scattering theory and to bound state problems, chaotic behaviour, large order perturbation theory, complex eigenvalues and quasistationary states, semiclassical methods, hyperaccurate wave functions, density functional theory, relativistic quantum theory, and quantum Monte Carlo methods.
