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
Atom (Ray Palmer) to restore the natives of Kandor to their full height, but is instead tricked into reviving a twisted Kryptonian cult, whose leader proceeds to crush Palmer and Kandor. Other re-imaginings of the Atom include an appearance in "League of Justice", an Elseworlds story portraying the Justice League in a "The Lord of the Rings"-type story where the Atom was recast as a wizard/fortune teller called "Atomus The Palmer". In "", Ray Palmer worked with a science consortium whose members at one point included Thomas Edison and Nikola Tesla. In "JLA: Rock Of Ages", the Atom is part of what remains
