Abstract

The results on {eta}`{pi}{sup 0} system produced in {pi}{sup -}p charge-exchange interactions at {pi}{sup -}-momenta 38 GeV/c and 100 GeV/c are presented. The 2{gamma} and {eta}{pi}{sup 0}{pi}{sup 0} modes of {eta}` decay corresponding to 4{gamma} and 8{gamma}-final state topologies have been detected. Background sources and the methods of its suppression are discussed. No statistically significant peaks are observed in the {eta}`{pi}{sup 0} mass spectrum in the range of 1.2GeV-2.1GeV. Upper limit for a{sub 2}{sup 0}(1320){yields}{eta}`{pi}{sup 0} branching ratio is obtained, BR<6x10{sup -3}. 9 refs.
