Radiative mechanism of lepton bound-state production
Akhiezer A. I. , Merenkov N. P.
The radiative mechanism of lepton bound-state formation is investigated. It results in real photon emission and bound-state production in a free lepton interaction. The cross sections for the corresponding processes are derived, and some figures given for the case of positronium formation in free electron-positron collisions. © 7995 American Institute of Physics.
