THE PRODUCTION OF REGGE RECURRENCES.

For resonance states lying on a given Regge trajectory, the two-body production mechanism as a function of the excitation of the recurrence state is discussed. A dual resonance model suggests general features for the Regge-Regge-particle coupling involved in such production. An application is made to the high energy production in πN → ππN of p , f$_{o}$ and g mesons with emphasis on the relative production cross-sections, the relative t dependences, the ratio of natural to unnatural parity exchange, and the helicity dependence.
