Atom was considered an indivisible particle of matter until some decades back. But incessant efforts of scientists have proved it wrong. It consists of three parts: electron, proton and neutron. Electron is the most significant and powerful of all, which carries a negative charge and remains in motion unstopped. Its motion provides energy, which has revolutionised the whole life of man. The theory of relativity and the quantum theory in its present form of wave mechanics. The study of the nucleus of the atom, in this book undertaken chiefly from the experimental point of view, and the structure and properties of the nucleus are discussed in the light of the experimental results. Elements of Atomic Physics has been conceptualized and designed keeping in mind the need of graduate and postgraduate students in physics for a comprehensive manual dealing with advanced atomic physics. The forces of the text is on recent advances in the ever-changing field of atomic physics, and how research attention is concentrated upon gaining insight into the most fundamental principles of the subject. The principles, concepts and practices have been delineated thoroughly along with detailed illustrations and diagrams aiding in better understanding.
