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 can fly and fire nuclear blasts from his hands (In the Golden Age, at least, lead is impervious to these blasts). Mister Atom appeared in an issue of the "Justice League Unlimited" comic book, where Doctor Sivana was trying to rebuild him with the help of a local gang. Atom and Sivana were eventually defeated by the Justice League, particularly Vibe. The character also appeared several times in the all-ages comic series "Billy Batson and the Magic of Shazam!"
