About electrons and position in triplet production: Some remarks

Taking into account the increasing interest in measuring high energy gamma ray polarization, Boldishev et. at ( 1994) [1]. published an extensive and very comprehensive work on the possibility of using the recoil electrons in the production of pairs on electrons. However, this work is based on using only 2 Feynmann diagrams of the 8 that the process has. This eliminates the difficulty of distinguishing, in the theory, which is the recoil...
