Normally the photons given off during Positron-Electron Annihilation
are two 510 KeV photons, but three photon Annihilation radiation
also occurs.
If the known Positron Anion (Ps-) collapses to a stable ~ 2 to 2.7 electron
mass bound particle Electronium (*e-) or (e- e+ e-) the most likely energy given off
as the binding energy (mass defect) are three photons of ~ 170 KeV each or
the equivalent of 1/3 of an electron mass.
Coincidentally the anomalous "2 Billion Deg" x-ray temperature achieved by
Sandia's Z Pinch of steel wires corresponds to the estimated 170 KeV
3-photon radiation for (*e-) formation, or possible disruption.
