The isoscalar-isovector (r-w) interferences in the exclusive reactions

near the w threshold leads to a distinct difference of the dielectron invariant
mass distributions depending on beam energy.
The strength of this effect is determined by the coupling of resonances to the nucleon
vector-meson channels and other resonance properties. Therefore, a combined analysis of the
se reactions can be usedas a tool for determining the baryon resonance dynamics.
