AbstractAbstract
[en] 2γ-event energy spectrum has been measured within the 0<=T<=300 MeV kinetic energy range. 2γ-quanta from the eta meson decay were produced on copper nuclei by 3.8 GeV/cπ--mesons at 180 deg angle in laboratory system. The 2γ-event spectrum in the mass interval 549+-50 MeV is presented as invariant cross section Ex(d3σ/d anti p3), where E and p are total energy and 2γ-event momentum, respectively. On the basis of experimental data the upper boundary for invariant cross section of meson generation in the π-Cu→eta (180 deg)X reaction is determined with the 90% level of reliability
