Query: Baryon Resonance Dynamics in pi N \to N V Reactions Near Threshold   The rho - omega interference in the exclusive reaction pi N \to N' e+ e- is
studied within a schematic model including the established baryon resonances up
to 1720 MeV. Near threshold the interference can be used to separate the
isoscalar part of the electromagnetic current. The role of various baryon
resonances is highlighted.
