The Wave Mechanics of Electrons In Metals

By S. Raimes Amsterdam: North-Holland Publishing Company Pp. xi + 367. Price 80s. The appearance of this book on the electron theory of metals by one who has contributed to the more recent developments of the theory, in which the conduction electrons are treated collectively rather than in the 'one-electron' approximation, has been awaited with interest. The reader would expect from the author a mature and 'digested' exposition of these rather more difficult aspects of the theory, and indeed he will find this in the book; but alas, it is all too brief, for much that could have been included is crowded out by a great deal of material of which the reader may readily find excellent expositions elsewhere.
