Abstract

The semiexclusive reaction [Formula Presented] has been studied at pion kinetic energies of 105 MeV and 115 MeV. Signatures from the production of the hypothetical [Formula Presented] resonance [Formula Presented] have been searched for in the invariant mass [Formula Presented] spectra. No hint for a dominant [Formula Presented] production, as anticipated from double charge exchange excitation functions on nuclei, has been found. The data are satisfactorily described by sequential single charge exchange. © 2002 The American Physical Society.
