exotic atom

[ik¦säd·ik ′ad·əm]
(atomic physics)
A system in which either the proton that forms the nucleus of a hydrogen atom is replaced by another particle (such as a muon, to form muonium, or a positron, to form positronium), one electron in an ordinary atom is replaced by another particle (such as a muon, pion, or antiproton), or both substitutions are made (as in antihydrogen).

Drawn from the proceedings of the XXII International Conference on Laser Spectroscopy (ICOL2015), held in Singapore in June and July of 2015, the eight papers in this volume discuss quantum walks with neutral atoms in state-dependent optical lattices; the role of muonic atoms in nuclear structure; the development and optimization of Doppler broadening thermometry using acetylene as a molecular target; antiferromagnetism with ultracold atoms; the generation and transfer of stable optical frequencies in optical clocks with trapped ions; precision measurement of the Newtonian gravitational constant by atom interferometry; optical sideband cooling in a Penning trap; and Bose-Einstein condensation of photons vs.
