The average multiplicity and inelasticity in π-meson production in the atmosphere

  • Published:
Il Nuovo Cimento (1955-1965)

Summary

The energy spectra of primary and secondary cosmic radiation are analysed to find the multiplicity-energy relation in the π-meson production in the atmosphere at the energy region from several GeV to some thousands GeV with the help of simplified considerations on the meson production by nucleus-nucleus collisions. The results being subjected to the assumed values of inelasticity suggest that the multiplicity-energy relation agrees with the formula of the type given by Fermi and Landau under the condition of a practically constant small inelasticity.

Riassunto

Si analizzano gli spettri energetici della radiazione cosmica primaria e secondaria per trovare la relazione molteplicità-energia nella produzione di mesoni π nell’atmosfera nell’intervallo energetico da alcuni GeV ad aloune migliaia di GeV con l’ausilio di considerazioni semplificate sulla produzione di mesoni per oollisione nuoleo-nucleo. Dai risultati, confrontati coi valori assunti per l’inelasticità, si rileva che la relazione molteplicità-energia si accorda con una formula del tipo di quella data da Fermi e Landau a condizione di avère debole inelasticità, praticamente costante.
