Summary

Measurements of ionization loss by relativistic charged particles have been made in helium, argon and xenon. The experimental results agree well with theory in the case of helium. In argon, and particularly in xenon, the relativistic rise in ionization found experimentally is less than that predicted theoretically. The measurements were made by the method of counting drops in a cloud chamber.

Riassunto

In elio, argon e xenon si sono eseguite misure della ionizzazione prodotta da particelle relativistiche cariche. Nel caso dell’elio i risultati sperimentali si accordano bene con la teoria. Nell’argon e particolarmente nello xenon l’aumento relativistico della ionizzazione trovato sperimentalmente è inferiore a quanto la teoria lascia prevedere. Le misure furono eseguite col metodo del conteggio delle gocce in una camera a nebbia.
