Production of relativistic positronium in collisions of photons and electrons with nuclei and atoms

S. R. Gevorkyan, E. A. Kuraev, A. Schiller +2

We consider the production of ultrarelativistic positronium (Ps) in $\gamma A\to Ps+A$ and $eA\to Ps+eA$ processes where $A$ is an atom or a nucleus with charge $Ze$. For the pho…
