Introduction to Atomic Physics

The study of atomic physics is crucial for understanding the fundamental principles of nature at a microscopic scale. This book aims to provide younger minds with the necessary knowledge and skills to explore atomic phenomena. It comprehensively covers historical breakthroughs in atomic theory, including mechanical models, the vector atomic model, and key experiments like the Stern-Gerlach experiment. Furthermore, it delves into advanced topics such as fine and hyperfine structure, the behavior of one-electron, alkali, and many-electron atoms, along with pre-quantum mechanical perspectives. To facilitate the learning experience, each unit concludes with worked-out examples, exercise problems, and questions designed for revision. The authors express gratitude towards their students and colleagues whose contributions have enriched this work. This book serves as an essential resource for developing a thorough understanding of atomic physics and its applications in modern science.
