Exotic Atoms

Abstract

An “ordinary” atom consists of a positively charged nucleus which interacts electromagnetically with electrons, leading to bound atomic states. Similar systems, in which an electron is replaced by any negatively charged particle other than an electron, are called “exotic” atoms. In 1947, soon after the discovery of the π meson, Wheeler(1) suggested the existence of such atoms. The first species to be observed were muonic atoms at Columbia(2) and π-mesonic (pionic) atoms at Rochester and Pittsburgh(3) in 1952–1953. Κ-mesonic (kaonic) atoms were first observed in 1965 at Argonne, (4) and 2, hyperonic(5) and antiprotonic atoms(6) were seen and investigated for the first time at CERN in 1970.
