Are there Jth order resonances of spin J?
It is suggested that the sequence ρ,A2,R,S,is a sequence of multipole resonances. Thus, the A2 is a doubled resonance, the R is a tripled resonance, and so on. This hypothesis is consistent with present experimental data. The multipole resonance hypothesis is related to narrow-width resonance models in which undesirable states are eliminated with the aid of satellite Veneziano terms. The high-energy behavior is similar to normal Regge Behavior. © 1970 The American Physical Society.
