Abstract
All presently available data on pionic double charge exchange on nucle i exhibit a resonance-like energy dependence near T(pi) = 50 MeV, whil e the angular distributions behave quite regularly. We show that these features find their natural explanation by a narrow resonance in the piNN-subsystem with J(P) = 0- and a mass of 2.065 GeV.
