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
Up An' Atom Base, Texas, and was re-configured as a TB-29 trainer in April 1950 by the Oklahoma City Air Materiel Area at Tinker Air Force Base. Its subsequent assignments were to: "Up An' Atom" was dropped from the Air Force inventory in November 1956. It was transferred to the U.S. Navy and used as a target at the Naval Ordnance Test Station at China Lake, California. Up An' Atom Up An' Atom was the name of a B-29 Superfortress (B-29-36-MO 44-27304, Victor number 88) configured during World War II in the Silverplate project to carry an atomic bomb.
