Summary
A multiplate cloud chamber was controlled by GM counters and those photographs were selected in which the directions of the shower axes could be determined eithera) from the directions of one or more energetic particles, orb) from the directions of parallel particles. From the distribution of the projected zenith angles of the shower axes the following values of the attenuation length (λ) were obtained: in the casea)λ= 85±5 gcm−2, and in the caseb) λ = 101±8 gcm−2.
Riassunto
Una camera a nebbia con più piastre era comandata da contatori GeigerMüller e si scelsero quelle fotografie nelle quali le direzioni degli assi dello sciame potevano essere determinatea) dalla direzione di una o più particelle energetiche, o b) dalle direzioni delle tracce parallele di particelle. Dalla distribuzione delle proiezioni degli angoli zenitali degli assi degli sciami si sono ottenuti i seguenti valori delle lunghezze di smorzamento (λ): nel casoa) λ = 85±5 gcm−2, e nel casob) λ= 101 ±8 g cm−2.
