A note on the inelastic contributions to the elastic scattering of high-energy electrons from helium

  • P. O. Davey
  • H. S. Valk


An estimate is made of the contribution of non-radiative inelastic processes to the elastic scattering of high-energy electrons from4He. It is shown that at the presently available energies and scattering angles the dominant process is electrodisintegration, and that this and other effects may be expected to give a correction to the differential elastic scattering cross-section of several percent, the maximum values occurring at high-energies and backward scattering angles.


Si valuta il contributo dei processi elastici non radiativi allo scattering elastico degli elettroni di alta energia derivanti da4He. Si dimostra che alle energie e sotto gli angoli di scattering attualmente disponibili il processo dominante è l’elettrodisintegrazione e che presumibilmente questo o altri effetti debbono apportare una correzione di alcuni percento alla sezione d’urto elastica differenziale, presentandosi i valori massimi alle alte energie e sotto angoli di scattering retrogradi.
