Abstract

The production ofηπ0 system inπ p charge-exchange interactions atπ momenta 38 GeV/c and 100 GeV/c has been studied. The 2γ and ηπ0π0 decay modes ofη leading to 4γ and 8γ final states respectively have been detected. No statistically significant peak is observed in theηπ0 mass spectrum in the range of 1.2 GeV÷2.1 GeV. An upper limit of 6·10−3 has been established for thea 2 0 (1320)→ηπ0 branching ratio.
