The Fundamentals of Atomic Physics

Atomic physics is the branch of physics that studies the structure and behavior of atoms, including the atomic nucleus and the electrons that surround it. Its primary concern is the arrangement of electrons around the nucleus and the mechanisms that lead to changes in these configurations. This field examines both neutral atoms and ions, as well as processes such as ionization and excitation through photon interactions or collisions with atomic and subatomic particles. Atomic physics provides foundational theories that support fields such as plasma physics and contribute to the understanding of atomic-level interactions in atmospheric physics. This book is a valuable compilation of topics, ranging from the basic to the most complex theories and principles in the field of atomic physics. It presents the complex subject in the most comprehensible and easy to understand language. This book will serve as a reference to a broad spectrum of readers.
