Isolated atoms[ edit ] Atomic physics primarily considers atoms in isolation. Atomic models will consist of a single nucleus that may be surrounded by one or more bound electrons. It is not concerned with the formation of molecules although much of the physics is identical , nor does it examine atoms in a solid state as condensed matter. It is concerned with processes such as ionization and excitation by photons or collisions with atomic particles. While modelling atoms in isolation may not seem realistic, if one considers atoms in a gas or plasma then the time-scales for atom-atom interactions are huge in comparison to the atomic processes that are generally considered.

About this product Description The study of atomic and molecular physics is a key component of undergraduate courses in physics, because of its fundamental importance to the understanding of many aspects of modern physics.
The aim of this new edition is to provide a unified account of the subject within an undergraduate framework, taking the opportunity to make improvements based on the teaching experience of users of the first edition, and cover important new developments in the subject.
Revised material on molecular structure and spectra. Extended material on electronic and atomic collisions. A new chapter describing applications based on the use of the maser and the laser, including laser spectroscopy, laser cooling and trapping of atoms, Bose Einstein condensation, atom lasers and atomic systems in intense laser fields. A new chapter describing other applications, including magnetic resonance, atom optics, atoms in cavities, ions in traps, atomic clocks and astrophysics.
Revised appendices include new material on molecules and updated tables of physical constants. Solutions of selected problems. Preface to the Second Edition. Preface to the First Edition. Electrons, photons and atoms.
The elements of quantum mechanics. One-electron atoms. Interaction of one-electron atoms with electomagnetic radiation. One-electron atoms: fine structure and hyperfine structure. Interaction of one-electron atoms with external electric and magnetic fields. Two-electron atoms. Interaction of many-electron atoms with electromagnetic radiation and with static electric and magnetic fields.
Molecular structure. Atomic collisions: basic concepts and potential scattering. Electron-atom collisions and atomic photoionisation. Atom-atom collisions. Masers, lasers and their interaction with atoms and molecules. Further developments and applications of atomic and molecular physics.
