Description

The partial widths of η'-meson decays into 2γ, ωγ, 3π0 and ηπ0π0 have been measured. Upper limits on η' decays into 3γ, π0γγ,2π0 and 4π0 are obtained. The linear-matrix-element slope for G-parity violating decay η' → 3π0 has been determined. The experiment has been performed with high accuracy at the 70 GeV IHEP accelerator. The hodoscope multiphoton spectrometer GAMS-2000 has been used to detect up to ten gamma-quanta from η' decays
