Building on ideas expressed in answer to What is angular momentum or spin of an electron? Why is it called spin if it has nothing to do with actual rotation? I think the mystery of spin can be explained by placing the diagram below in 3-dimensiona. This in-depth textbook with a focus on atom-light interactions prepares students for research in a fast-growing and dynamic field. Intended to accompany the laser-induced revolution in atomic physics, it is a comprehensive text for the emerging era in atomic, molecular and optical by: 4.

Atomic, Molecular, and Chemical Physics. The Atomic, Molecular, and Chemical Physics group focuses on interactions of atoms, molecules, electrons and photons at low temperatures and low energies. Our programs include both experimental and theoretical projects, many of which entail collaborations within and outside the Department. Quantum Collisions and Confinement of Atomic and Molecular Species, and Photons His primary areas of interest include photoabsorption processes in free/confined atoms, molecules and ions. He is a former president of the Indian Society of Atomic and Molecular Physics (ISAMP), and is a member of several national and international scientific.

atoms and molecules), and direct ionization by electron impact. The energy quantum of excitation electronically excited states of atoms and molecules serves as a characteris-tic energy scale for electrons. Electron collisions with neutral particles result in angular scattering and energy loss of elec-trons. The relative importance of these two.   Since the early days of modem physics spectroscopic techniques have been employed as a powerful tool to assess existing theoretical models and to uncover novel phenomena that promote the development of new concepts. Conventionally, the system to be probed is prepared in a well-defined state. Upon a controlled perturbation one measures then the spectrum of a single particle (electron, .
