Features: This book is the fifth volume of the "Fundamentals of Physics" series, which is an 21st Century Curriculum Textbook approved by the Ministry of Education. It primarily covers atomic physics and molecular physics. Compared to traditional content, it places greater emphasis on the interaction between radiation fields and atoms. Chapter 1 introduces atomic physics before quantum mechanics, including a quantitative description of spectral lines and a discussion of transitions between two energy levels. Chapter 2 provides an introduction to quantum mechanics. Chapters 3 and 4, respectively, introduce the structure and spectra of alkali metal atoms and complex atoms. Chapter 5 discusses atoms in a magnetic field, offering an in-depth introduction to magnetic resonance. Chapter 6 explores the interaction between radiation fields and atoms, presenting both classical theory (with quantum mechanical corrections) and clarifying resonance absorption and dispersion processes. Building on this, it analyzes quantum amplification and oscillation (including laser principles) as well as the mechanical force of resonance radiation fields on atoms. Chapter 7 covers molecular structure and spectra. As a supplementary section, Chapter 8 provides some knowledge of solid-state physics. In addition to the main text, the book includes extensive appendices, as well as thought questions and exercises, allowing readers to gain a deeper understanding of the latest developments in atomic physics and experience the joy of applying fundamental physics knowledge, connecting theory to practice, and solving problems. This book can serve as a textbook for foundational physics courses in comprehensive universities for science and engineering majors, as well as a reference for physics teachers in other higher education institutions and high schools for teaching or self-study purposes.
