Summary
The lateral density distribution of electrons in air showers has been observed at 3260 m altitude with an assembly of ionization chambers. The resolution was about 20 cm for 1/r peaks within the main array of 18 chambers. The absolute intensity of showers of size 105<N<106 agrees with previous observations. Multiple peaks were observed and their spatial distribution indicates a mean separation of about 50 cm. The problem of a model for the production of the multiple-cored showers that is consistent with the observations is described.
Riassunto
La distribuzione della densità laterale degli elettroni negli sciami atmosferici è stata osservata a 3 260 m s.l.m. con una combinazione di camere di ionizzazione. La risoluzione era di circa 20 cm per massini di 1/r entro il complesso principale di 18 camere. L’intensità assoluta degli sciami di dimensioni 105<N<106 si accorda con osservazioni precedenti. Sono stati osservati massimi multipli e la loro distribuzione spaziale indica una separazione media di circa 50 cm. Si descrive il problema di un modello per la produzione degli sciami a noccioli multipli compatibile con le osservazioni.
