** About the book** This introduction to quantum mechanics, written at the senior-graduate level, emphasizes the physical basis of the subject, without undue neglect of its mathematical aspects. A noteworthy feature of the book is its careful, detailed explanation of scattering, matrix theory, transformation theory, angular momentum, radiation, and perturbation theory. Prominence is given to the role of symmetry operations and to the essentially algebraic structure of quantum-mechanical theory. |
