Article révisé par les pairs
Résumé : A comparison has been made between the theory of electron pair production by photons and experimental data, for energies up to 400 MeV. The following points have been analysed: 1) Energy partition between the two members of the pair; 2) Statistical distribution of the momentum transfer to the pair; 3) Distribution of the angle of divergence of the pair. © 1953 Società Italiana di Fisica.
