Sull'eccesso positivo della radiazione cosmica

  • Published:
Il Nuovo Cimento (1943-1954)

Riassunto

Si considera il problema dell'eccesso positivo esaminando in particolare il contributo portato dalla componente primaria protonica nell'urto protone-protone, che si ammette abbia luogo con emissione multipla di mesoni (numero medio 6 per urto), e quello dovuto all'asimmetria fra mesoni positivi e negativi dipendente dall'azione coulombiana del nucleo urtato sui mesoni diffusi. Per quanto riguarda un terzo contributo, non trascurabile in quota e dovuto al residuo della componente primaria, mancano ancora dati sperimentali sufficientemente precisi.

Summary

The question of the positive excess is considered examining particularly the contribution brought by the primary protonic component in the proton-proton collision, which is admitted to take place with multiple meson emission (meanly 6 for each collision), and the contribution due to the asymmetry between positive and negative mesons depending on the coulombian influence of the stricken nucleus on the diffused mesons. On a third contribution, not negligile at high levels and due to the rest of the primary component, we have not yet sufficiently accurate experimental results.
