The first chapter discusses the theory of slow neutron radiative capture, while the second chapter covers fast neutron radiative capture. Chapter III talks about methods for calculating neutron capture cross sections and gamma-ray spectra, while Chapter IV deals with the measurement techniques for radiative neutron capture, and Chapter V discusses neutron capture processes in fission reactors. The sixth chapter covers applications to stellar nucleosynthesis and the seventh chapter covers the practical uses of neutron capture gamma-ray spectroscopy. The book is meant for the use of graduate students who are knowledgeable about basic nuclear physics.
