Abstract：
Using a very light silica aerogel sample as the o-Ps source to reduce the scattered γ rays and a high purity Ge (HPGe) γ energy spectrometer with a precise timing channel for event selection, the continuous γ ray energy spectrum from o-Ps 3γ decay has been measured in the whole spectrum range. The result is in a good agreement with the result of Ore-Powell theoretical calculation.
