Air-shower transition in water; interpretation of under-water decoherence curves

  • W. E. Hazen
Article

Summary

Under-water decoherence curves taken with ionization chambers byEl-Mofti are reinterpreted by means of a more detailed calculation. The observations require no core multiplicity for interpretation but are consistent with the occasional occurrence of multiplecored showers with core separations ≲one meter. The rate versus depth in water indicates a rather soft energy spectrum in air.

Riassunto

Le curve di transizione per sciami d'aria ottenute con camere di ionizzazione daEl-Mofti sono state nuovamente interpretate per mezzo di calcoli più particolareggiati. Le osservazioni sperimentali non richiedono l'ipotesi che i «cores» siano sempre multipli, ma occasionalmente. Nel qual caso, la separazione è ≲ 1 m. La frequenza in funzione della profondità in acqua indica uno spettro di bassa energia.
