METHOD OF IN-FLIGHT PRODUCTION OF EXOTIC SYSTEMS IN CHARGE-EXCHANGE REACTIONS

An efficient method for the production of exotic systems in charge-exc hange reactions is proposed. In this method the reactions take place i n-flight in the overlapping area of two particle beams. Advantages of this method are large cross sections of the charge exchange reactions, and the absence of losses and interaction with the medium. The produc tion of positronium, protonium antihydrogen and ions of the antiproton ic helium isoelectronic sequence is considered, possible yields are es timated and some problems of measurement on the beam of the produced p articles are discussed.
