Introduction to Atomic and Nuclear Physics

This book represents a first approach to the physics of the atom and the nucleus. It is considered most desirable that all graduates in pure science, even those who are to specialize in subjects other than physics, should be familiar with the ideas of atomic physics in the broadest sense.This book also provides the groundwork for physics honours students. It is also useful for applied science students in electrical and mechanical engineering and in metalurgy. For al such students of pure and applied science, as well as for students following parallel courses in coleges of advanced technology, this book should provide a helpful introduction. With the inclusion of atomic and nudear physics in the syllabus of high schools many of the chapters should prove useful to the students at high school level. In short this book has been written mainly for students in the high schooland in the first two years at university, international union ot Pure and Applied Khysics prescnbes the use ot S.l. units (Syst&me International d'Unites).This book has been written in S.l. units to conform to the international standards. Appendix A includes S.l. units and those familiar mainly with c.g.s. units svillfind it advantageous. The chapter on new unstable partides gives some indication of their interpretation. Carbon 12 instead of oxygen 16 has been used as unit of atomic mass.The quantitative work in the book is consolidated by numerous problems, some of which are worked out in detail. Additional problems have been added at the end of each chapter. Although many of the problems amount to little more than numerical substitutions, experience has shown that they give the student confidence and provide useful ideas about orders of magnitude.
