This textbook on nuclear structure and reactions is for students who have completed an introductory course on quantum mechanics. The appendices, four of which are new to this edition, describe some advanced topics in more detail than is appropriate in the main text. From reviews of the first edition: 'The difficulties of treating these subjects at this level are overcome very successfully by judicious use of simplified calculations, illuminated by penetrating comments revealing a deep understanding of the subject. Indeed, there are few professional nuclear physicists who would not find it a rewarding experience to read this book.' Nature
