Experimental density matrices of the vector mesons and isobars produced in reactions of the form πB→VB and πB→VΔ are compared with predictions obtained by assuming particular couplings at the Regge baryon-baryon vertex. Couplings are classified according to the total angular momentum J (orbital combined with intrinsic) of the Regge trajectory relative to the incident nucleon in the direct channel. For the πB→VΔ case, it is found that the present Regge-pole treatment of unequal-mass kinematics allows one to distinguish between couplings for different J, and that all data are consistent with J=1. Data for πB→VB charge-exchange reactions are also consistent with J=1 dominance.
