TL;DR: In this paper, the results of a measurement of pp annihilation at rest into ηηπ 0 were presented assuming a resonance dominated model for the annihilation process, and an isoscalar J PC =0 ++ resonance decaying into γπ 0 was observed with a mass of 1560±25 MeV/c 2 and a width of 245±50 MeV /c 2.
