We do not see any peak at 511keV in the GS5.2 spectrum. So, this reaction must not be happening at any significant rate. In fact, there can be no significant amount of positrons for lack of the 511keV peak.
Focardi did report some evidence of the 511keV peak in one of his papers, but I think he later retracted it.
