Summary
In this paper a method is discussed to determine the connection between the number of δ-electrons, extracted by distant collision of an ultrarelativistic particle with the electrons of a medium, and theγ=1/√1−(v/c)2 of the particle. The Weizsäcker-Williams method is used to reduce the problem to a photoelectric effect. Hydrogen atom type eigenfunctions are used to describe the metallic electrons. Errors due to this approximation are estimated.
Riassunto
In questo lavoro si discute un metodo per determinare la connessione fra il numero di elettroni δ estratti da una particella ultrarelativistica per collisione cogli elettroni di un mezzo materiale e ilγ=1/√1−(v/c)2 della particella stessa. Si usa il metodo di Weizsäcker-Williams per ridurre il problema allo studio di un effetto fotoelettrico. Per descrivere gli elettroni metallici si usano autofunzioni tipo atomo di idrogeno e si valutano anche gli errori dovuti a questa approssimazione.
