Summary
Second order Born approximation of electron-positron elastic potential scattering from extended nuclei is calculated, and a general formula is given for any charge distribution. The dependence of (σ−−σ+)/σ− from particular charge distributions is analysed and discussed.
Riassunto
Viene calcolata in seconda approssimazione di Born la sezione d’urto per lo scattering elastico, e di potenziale, di elettroni positivi e negativi da parte di nuclei a dimensione finita; si ottiene un’espressione generale valida per ogni distribuzione di carica. Viene inoltre esaminata e discussa la dipendenza di (σ−−σ+)/σ− da differenti distribuzioni di carica.

For sin θ/2>0.55, (σ−−σ+)/σ− increases rapidly indicating that the effect discussed in the note of p. 792 is present.
