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
Mister Atom Mister Atom Mister Atom is a fictional comic book supervillain, a radioactive robot who is regularly seen as an enemy of Captain Marvel. Mister Atom first appeared in "Captain Marvel Adventures" #78 and was created by Otto Binder and C. C. Beck. Mister Atom was created by Dr. Charles Langley in a story in "Captain Marvel Adventures" #78. His body was constructed first, and then Langley charged the robot with radioactive energy. The spark that gave the robot life also ended the life of his creator. Super-charged with a nuclear reactor and armed with a deadly mind, Mister Atom went
