BOOK REVIEWS ZICHICHI lED.), Laws o/hadronic matter, 1973 lnternat. School o f Subnuclear Physics, Erice, 8-26 July 1973 (Academic Press, New York, 1975) $49. The title o f the book promises something which is hard to live up to! The volume contains lectures and seminars given at the l lth Course of the International School of Subnuclear Physics '" Ettore M a j o r a n a " held at Erice, July 1973. The book is divided into two parts. Part A contains theoretical lectures and seminars and part B is mainly devoted to the features of experimental data in high energy physics and their possible interpretations, Part A begins with a review of rigorous results one may deduce for r -1 potentials and its applications to electromagnetic and gravitational interactions (W. Thirring). The following lectures deal with symmetry breaking be it spontaneous or dynamical, quantization schemes in field theory, and dual models. These lectures give a good introduction to the topics covered which still occupy a central position in active research and are quite useful for theoretical physicists who want to learn these subjects. Part A ends with lectures primarily on vector dominance and the theore-

The present volume contains lectures, seminars and discussions presented at the 12th Course of the International School on Subnuclear Physics. The lecture series presented deal mainly with theoretical and experimental topics o f current interest within high energy physics. A m o n g the theoretical topics are the nature of the pomeron, the massive quark model, deep inelastic phenomena and physics of diffractive excitation and large transverse m o m e n t u m phenomena. Also a great deal o f interest is devoted to the possible interpretations of the puzzling results from electron-positron annihilation into hadrons. Indeed the School was held only a few months before the discovery o f the new particles at the Brookhaven National Laboratory and at SLAC. Since then the electron positron annihilation puzzle, although remaining still unsolved, has changed much of its original character. Nevertheless the series of theoretical lectures, on this topic, by C. H. Llewellyn Smith

P.J. OUSEPH, Introduction to nuclear detectors (Plenum Press, New York, London, Washington. Boston, 1975) pp. 194. The purpose of the book is to give a description of nuclear radiation detectors for detector users from other fields than nuclear science, such as scientists arid technicians in chemistry, geology, biochemistry, and medicine. In a relatively small volume the author manages to cover his topic quite well. Approximately one third of the book is devoted to basic, elementary facts such as the interaction of radiation with matter. the laws of radioactive decay and counting statistics. The remainder is divided almost equally a m o n g descriptions o f gas

tical aspects of rising cross-sections and large m o m e n t u m transfer phenomena. The experimental reviews and results presented in part B are bound to be a bit outdated by the fairly long delay to publication o f these proceedings, and fuller discussions o f newer experimental results can be found elsewhere. Ample space is given to the discussion o f recent high energy data on proton proton collisions from the C E R N ISR and the presentations o f e . g . E . L . Berger and U. Amaldi are pedagogical and enjoyable to read. The electromagnetic interactions are nicely reviewed by S. C. C. Ting and his continuous search for vector mesons, which later led to the discovery of the J-particle, is discussed. A. H. Rosenfeld gives guidelines of how to go from Argand diagrams to physics. In spite o f the fact that this volume does not establish any new laws of hadronic physics the pedagogical treatment of the various subjects as well as the extensive discussion following each lecture to clarify points of uncertainty is a merit that makes this book a useful supplementary reading for courses in high energy physics.

provides a good introduction to the subject. Several lectures and seminars deal with the weak neutral current effects. A portion of the book is devoted to a discussion o f recent experimental findings on neutral currents from C E R N , Fermilab and the Argonne National Laboratory. The possibility o f spin rotation effects in neutron optics due to weak neutral currents is discussed in a seminar. Detectability o f charmed particles and other "'missing particles", discussed in the present volume are quite relevant to the new trends in particle physics since the School was held. A m o n g the seminars, the suggestion o f possible existence o f abnormal nuclear states is specially interesting. A m o n g the miscellaneous topics presented are short-range correlations in nuclear matter and a discussion o f black holes. A nice and useful feature o f the book is that the lectures and seminars are generally followed by ample discussions. With a large variety o f interesting and well presented topics it provides useful supplementary reading for courses in high energy physics. G. JARLSKOG

counters, scintillation counters and semiconductor detectors. The text is always quite elementary with very little mathematics or formulae and it should be easy to read for a non-specialist, but still it has been possible to include a substantial a m o u n t o f recent developments. The illustrations are informative and up to the point. All these facts taken together make the book a useful contribution to the existing literature on radiation detectors and it will probably well fulfill its purpose. The book does not deal with nuclear detectors as they are used in connection with accelerator-produced ions and it is not, nor is it intended to be, very useful for specialists in physics or nuclear science.
