Exotic atom to weak, electromagnetic and gravitational forces, muonic atoms are governed to very high precision by the electromagnetic interaction. Since a muon is more massive than an electron, the Bohr orbits are closer to the nucleus in a muonic atom than in an ordinary atom, and corrections due to quantum electrodynamics are more important. Study of muonic atoms' energy levels as well as transition rates from excited states to the ground state therefore provide experimental tests of quantum electrodynamics. Muon-catalyzed fusion is a technical application of muonic atoms. A "hadronic atom" is an atom in which one or more of the
Olaf—An Atom he recovers, alone and forgotten by those he has helped. He then moves aimlessly along. Directed by Anthony O'Sullivan and written by William E. Wing, "Olaf—An Atom" was produced by the Biograph Company and released May 19, 1913, in the United States. The drama was released August 4, 1913, in the United Kingdom. The film was retitled "The Wanderer" and re-released by the Aywon Film Corporation, a New York City company formed in early 1919. Aywon reissued films including the Biograph Company short films, which were often lengthened by the addition of intertitles. Olaf—An Atom Olaf—An Atom is a 1913
