✦ Synopsis

John Wiley & Sons, New York, 1984, 414 pp.
The object of this book is to present a balanced overview of the computational methods currently available for the solution of neutron transport problems encountered in engineering analysis. With changes only in the interaction laws contained in the cross section data, much of the text is equally applicable to other neutral particles, most particularly gamma rays. Moreover, several of the numerical methods developed for the linear equations of neutral particle transport are finding increased use in conjunction with nonlinear transport problems, such as those encountered in gas dynamics, plasma physics, and electron transport.
An attempt has been made to make the book reasonably self-contained in the hope that it may serve both as a text for first-year graduate students and as a reference to the practicing engineer. The subject matter relates strongly to the physics of nuclear reactors and radiation shielding on the one hand and numerical analysis on the other. Previous exposure to an introductory course in reactor theory is very helpful. For while we attempt to include all the necessary physical concepts, the choice of an effective computational method most often rests strongly on a thorough understanding of the underlying physics of the problem. A mathematics background through linear algebra and differential equations is presumed.
