This comprehensive text provides an introduction to basic nuclear physics, including nuclear decays and reactions and nuclear structure, while covering the essential areas of basic research and practical applications. Its emphasis on phenomonology and the results of real experiments distinguish this from all other texts available. Discussions of theory are reinforced with examples which illustrate and apply the theoretical formulism, thus aiding students in their reading and analysis of current literature. The text is designed to provide a core of material for students with minimal background in mathematics or quantum theory and offers more sophisticated material in separate sections.

    This v.ork began as a collaborative attempt vith David Halliday to revise ant update the second edition of his classic text lnrroductory .f>./uclear Physics (}\;ev 'l'ork: \\iiley. 1955). As the project evolved. it became clear that. to othei commitments. Professor Halliday \vould be able to devote only limited time t< the project and he therefore volunteered to remove himself from active participa tion. a proposal to \vhich I reluctantly and regretfully agreed. He was kine enou~1 lC sign 0vt>r to me the rights to use the material from the previou~ edition

    I first encountered Hah11.iay:. lcXl ci~ ..... .,ndergraduate physics major. and ii v. as perhaps my first real introduction to nuclear physics. I recall being impressec by iti; clarity and ill> readability. and in preparing this nev. version. I have tried tc preserve these elements. which are among the strengths of the previous work.

    Audience This text is written primarily for an undergraduate audience. but could be used in introductory graduate surveys of nuclear physics as v.ell. l t can be used specifically for physics majors as part of a survey of modern physics. but could (with an appropriate selection of material) serve as an introductory course for other areas of nuclear science and technology. including nuclear chemistry. nuclear engineering, radiation biology. and nuclear medicine.

    Background It is expected that students have a previous background in quan-tum physics. either at the introductory level !such as the author's text Modern Physics (Nev.: York: Wiley, 1983)] or at a more advanced. but still undergraduate level. (A brief summary of the needed quantum background is given in Chapter 2.) The text is therefore designed in a" two-track"' mode, so that the material that requires the advanced work in quantum mechanics, for instance. transition probabilities or matrix elements, can be separated from the rest of the text by skipping those sections that require such a background. This can be done without interrupting the logical flow of the discussion.

    Mathematical background at the level of differential equations should be sufficient for most applications.

    Emphasis There are two features that distinguish the pr-esent book.. The first is the emphasis on breadth. The presentation of a broad selection of material permits the instructor to tailor a curriculum to meet the needs of any particular





    student audience. The complete text is somewhat short for a full-year course, but too long for a course of quarter or semester length. The instructor is therefore able to select material that will provide students with the broadest possible introduction to the field of nuclear physics. consistent \vith the time available for the course.

    The second feature is the unabashedly experimental and phenomenological emphasis and orientation of the presentation. -The discussions of decay and reaction phenomena are accompanied with examples of experimental studies from the literature. These examples have been carefully selected following searches for papers that present data in the clearest possible manner and that relate most directly to the matter under discussion. These original experiments are discussed. often with accompanying diagrams of apparatus. and results wirh uncertainties are given. all in the attempt to convince students that progress in nuclear physics sprang not exclusively from the forehead of Fermi. but instead has been painstakingly won in the laboratory. At the same time. the rationale and motivation for the experiments are discussed. and their contributions to the theory are emphasized.

    Organization The book is divided into four units: Basic Nuclear Structure. Nuclear Decay and Radioactivity. Nuclear Reactions. and Extensions and t\.ppli-cations. The first unit presents background material on nuclear sizes and shapes. discusses the two-nucleon problem. and presents an introduction to nuclear models. These latter two topics can be skipped without loss of continuity in an abbreviated course. The second unit on decay and radioactivity presents the traditional topics. with ne\v material included to bring nuclear decay nearly into the current era (the recentlv discovered heavv'' decav modes. such as 14C. , , . double f3 decay, /3-delayed nucleon emission. Mossbauer dfect. and so on). The third unit surveys nuclear reactions. including fission and fusion and their applications; The final unit deals with topics that fall only loosely under the nuclear physics classification. including hyperfine interactions. particle physics. nuclear astrophysics. and general applications including nuclear medicine. The emphasis here is on the overlap \Vith other physics and nonphysics specialties. including atomic physics, high-energy physics. cosmology. chemistry. and medi-cine. Much of this material, particularly in Chapters 18 and 19. represents accomplishments of the last couple of years and therefore. as in all such volatile areas. may be outdated before the book is published. Even if this should occur. however, the instructor is presented with a golden opportunity to make important points about progress in science. Chapter 20 features applications involving similarly recent developments, such as PET scans. The material in this last unit builds to a considerable degree on the previous material: it would be very
