Theories of the Fine Structure Constant α3602 ± 0. 00021 for the electromagnetic coupling strength is still a mystery, and has provoked much interesting theoretical speculation. For purposes of discussion, the speculations may be divided roughly into four general types: (a) Theories in which . is cosmologically determined; (b) Theories in

Exotic Atomsre bound in the Coulomb field of an atomic nucleus. The exotic atoms are essentially hydrogen-like atoms except for their unusually large energy scales and drastically reduced orbital radii, hence the name. Their life spans from birth to death last only for very brief moments. The transient existenc

Theoretical Study of Atomic Rydberg Statesth a 10. -fold improvement in resolution over the conventional spectroscopic methods, makes it possible for the first time to obtain accurate details on the previously unresolved electrostatic fine structures. As emphasized by those authors, the physics of the atomic Rydberg states holds special the

Fine Structure and Hyperfine Structure of the Helium Negative Ionents can be performed to high precision and provide an excellent test of the theory of three-electron atomic systems. Studies of one- and two-electron systems have been very fruitful. The work of Lamb and others on the fine structure of hydrogen has provided a cornerstone of quantum electrodynamics
