Sažetak
The dynamics of the eta→ 3pi^0 decay have been studied with the Crystal Ball multiphoton spectrometer and the TAPS calorimeter. Bremsstrahlung photons produced by the 1.5-GeV electron beam of the Mainz microtron MAMI-C and tagged by the Glasgow photon spectrometer were used for eta-meson production. The analysis of 3×10^6 gamma p→ eta p→ 3 pi^0 p→ 6 gama p events yields the value alpha = -0.032 +/- 0.003 for the eta→ 3pi^0 slope parameter, which agrees with the majority of recent experimental results and has the smallest uncertainty. The pi^0pi^0 invariant-mass spectrum was investigated for the occurrence of a cusplike structure in the vicinity of the pi^+pi^-threshold. The observed effect is small and does not affect our measured value for the slope parameter.
