The exchange interaction is manifested not only between identical particles but also between any identical objects or systems. The exchange interaction is responsible for the pairing of atomic electrons in the orthoboson S=1 with the formation of a Bose-Einstein condensate in a strong magnetic field. Resonant interference exchange interaction occurs between an object and a system that has resonant R-states with this object. The RIEX-interaction explains the possibility of carrying out reactions of cold fusion and reactions of low-energy transmutation of chemical elements. The RIEX-interaction is also realized between systems with excited identical resonant R-states. Since the resonant interaction between objects is, in fact, a RIEX-interaction, it is based on all fundamental interactions.
