Abstract Monoenergetic peaks have been searched in the inclusive gamma ray spectrum from oPs decay. For axion mass 60keV to 970keV the 90% confidence level limits on the rabtio R of single gamma ray to three gamma ray decay from oPs 6 x10-4 to 6x10-5 without the assumption of the penetrating axions.
