TL;DR: In this article, the high-energy part of the spectrum was used to deduce branching ratios for the so far unobserved annihilation channels: R(p p →π 0 ω) = (2.38 ± 0.65)%, R( p p → π 0 η ) = (0.82 ± 0.04)% and an upper limit for the π0η′ channel was deduced.

TL;DR: In this paper, the γ spectrum associated with p p annihilation on 4He at rest was measured, showing two peaks, at energies of 161.9 and 203.0 MeV, corresponding to intermediate narrow states of masses which seem to be related to states found in p p annihilations.
