Summary
This paper is devoted to the study of the relations between the photon and electron-processes in the two-body systems for all multipoles. It is shown that all the multipoles, both electric and magnetic, with the exception of the even electric ones, are determined in photon and electron phenomena by the same parameters. For the even electric multipoles the electron disintegration involves the zero-zero transitions which are not present in the photodisintegration. The construction of the interference terms between different multipoles is discussed.
Riassunto
Si studiano le relazioni tra foto ed elettrodisintegrazione in due corpi per ogni multipolo. Si dimostra che per tutti i multipoli, elettrici e magnetici, eccetto quelli elettrici pari, le sezioni d’urto di foto ed elettrodisintegrazione sono determinate dagli stessi parametri. Per i multipoli elettrici pari 1’elettrodisintegrazione comprende le transizioni zero-zero che non sono presenti nella fotodisintegrazione. Si discute pure la costruzione dei termini di interferenza tra differenti multipoli.

In the general case, the modification consists mainly of the change of some factors in formulas (8′) and (9′), changes which have no influence in the final formula we are deriving.

Actually the two amplitudes are coherent, however the cross-terms vanish after spin averaging.
