Query: Experimental Indication of Existence of Extra Light-Vector Mesons
  omega'(1.3) and rho'(1.3)   Mass distributions of pi^+ pi^- pi^0 and omega pi^0 systems in the e^+ e^-
annihilation obtained by the several experiments are analyzed. We obtain
indication of light-vector mesons omega'(1.3) and rho'(1.3) in the lower mass
region. Those states are expected to exist in the U~(12)-classification scheme.
