Jackson's posthumously published textbook, A Course on Quantum Mechanics, covers quantum mechanics at an advanced level, presenting fundamental principles and techniques including the Schrödinger and Heisenberg representations, angular momentum, perturbation theory, scattering, quantum theory of radiation, and relativistic quantum mechanics. Particular attention is devoted to the WKB and eikonal approximations, which can be applied to a broad range of physical circumstances. An especially thorough treatment is given to atomic physics. The principles of quantum mechanics are illustrated in applications to atomic, nuclear, particle, and condensed matter physics, demonstrating that quantum mechanics provides a quantitative understanding of matter and light.The book is drawn directly from Jackson’s detailed lecture notes and problem sets. It is edited by colleague and former student Robert N. Cahn, who has taken care to preserve Jackson’s unique style. The textbook is notable for its origi
