Quantum Mechanics

The central role of quantum mechanics, as a unifying principle in contemporary
physics, is reflected in the training of physicists who take a common course, whether
they expect to specialize in atomic, molecular, nuclear, or particle physics, solid
state physics, qmtntum optics, quantum electronics, or quantum chemistry. This book
was written for such a course as a comprehensive introduction to the principles of
quantum mechanics and to their application in the subfields of physics.
The first edition of this book was published in 1961, the second in 1970. At
that time there were few graduate-level texts available to choose from. Now there
are many, but I was encouraged by colleagues and students to embark on a further
revision of this bo
