Polarization effects in bremsstrahlung

  • G. Böbel


In pursuance of a method devised byLipps andTolhoek, the differential cross-section of bremsstrahlung is written as a sum of eight terms, each correlating the different polarizations of the electron in the initial and final states and of the emitted photon (Sect. 1). The formulae of Bethe and Heitler and of May, Gluckstern and others are obtained as particular cases (Sect. 2) and discussion is also carried on as to the emission of circularly polarized photons from electrons having longitudinal and transversal spin respectively (Sect. 3).


Seguendo un metodo ideato da Lipps e Tolhoek si esprime la sezione d’urto differenziale della bremsstrahlung come la somma di otto termini, che mettono in correlazione le differenti polarizzazioni dell’elettrone negli stati iniziale e finale e del fotone emesso (Sez. 1). Le formule di Bethe e Heitler e di May, Gluckstern e altri si ottengono come casi particolari (Sez. 2) e si discute anche l’emissione di fotoni polarizzati circolarmente da elettroni con spin rispettivamente longitudinale e trasversale.
