Abstract

An estimate has been made of the trident crosssection for electrons of energy between 1 and 10 GeV Energy determinations were made by scattering measurements on each track under conditions where the effects of spurious scattering have been shown to be negligible In a total track length of 219 cm the estimated number of true tridents was found to be 3 as compared with 24 expected from theory Even on the basis of this small number of events there is a marked discrepancy between our results and those of previous experiments at high energies Eeasons for this discrepancy are discussedSi è stimata la sezione d’urto dei tridenti prodotti da elettroni da I e 10 GeV Le determinazioni dell’energia sono state effettuate per mezzo di misure di scattering su ogni tracoia in condizioni in cui gli effetti dello scattering spurio risultavano trascurabili Il numero di tridenti veri presenti in una lunghezza totale di traccia di 219 cm è risultato 3 contro i 24 predetti dalla teoria Anche in base a tale piccolo numero di eventi si ha una marcata discrepanza tra i nostri risultati e quelli di precedenti esperimenti ad alte energie Si discutono le ragioni di tale discrepanza
