Positronium formation for atoms with zero threshold energy

, 2002
Theoretical investigations are performed for positronium formation in positron collisions with a one-electron model atom which has zero threshold energy for positronium formation.

Collimated positronium production from gases [PDF]

New data for positronium beam production efficiency are presented. As a converter of positrons to forward-going positronium, O2 has been found to be as good as CO2 from 250 to 400 eV.

Formation of positronium in helium gas

, 1973
The formation of positronium in helium gas under an applied electric field has been investigated in order to derive a value for the momentum-transfer cross section, (σ m, of positrons on helium atoms.
