Quantum theory

Quantum Theory, Volume II: Aggregates of Particles presents the quantal treatment of systems of particles, including complex atoms, molecules, liquids, and solids. This book discusses the fundamentals and applications of quantum theory. Organized into seven chapters, this volume begins with an overview of the detailed information concerning the structure of complex atoms that is obtained from spectroscopic observations. This text then explains group theory as a branch of pure mathematics that can be applied to problems as diverse as the structure of crystals and the theory of equations. Other
