The authors describe a mathematical theory of a system of Fermions in a central field. This model describes systems of interacting particles like electrons in the atom or protons and neutrons in the nucleus. Their topics include the single particle shell model, tensor algebra in two particle systems, and three or more particle systems. The text emphasizes physical science over mathematics, and readers should be familiar with elementary quantum mechanics. This is a reprint of the original published in 1963 by Academic Press.
