Oks E. Simple Atomic and Molecular Systems: New results and applications

IOP Publishing Ltd, 2021. — 127 p. — ISBN 978-0-7503-3677-2.Simple atoms are atoms consisting of no more than three particles. They are the test-bench of atomic physics and quantum mechanics. This book presents these findings, bridging the gap between textbook descriptions of these systems and the latest research.
This book is devoted to simple atomic and molecular systems—specifically to systems consisting of no more than three particles. Simple atomic and molecular systems are the test-bench of atomic and molecular physics in general and of quantum mechanics in particular. This is because simple atomic and molecular systems may allow analytical solutions, not only as an isolated system but also in certain environments—the solutions revealing a rich physics despite the systems being simple. In addition, simple atomic and molecular systems and the phenomena involving them sometimes have unexpected similarities with some astrophysical objects and phenomenaIntroduction
