On the momentum spectrum of particles in cosmic ray jets

  • Published:
Il Nuovo Cimento (1955-1965)

Summary

It is shown that the form of momentum spectrum of jet particles is essentially dependent on the degree of anisotropy of the angular distribution, and thate.g. the form dp/p 2 corresponds to a definite « medium » anisotropy. Integral spectra of directly measured values ofp indicate a systematic decrease of transversal momenta in the vicinity of the axis and of theπ/2-plane in C.M. system.

Riassunto

Si mostra che la forma dello spettro della quantità di moto dei getti è essenzialmente dipendente dal grado di anisotropia delle distribuzioni angolari, e che, p. es., la forma dp/p 2 corrisponde ad una definita anisotropia del mezzo. Spettri integrali di valori dip misurati direttamente indicano una diminuizione sistematica dei momenti trasversali nella vicinanza dell’asse e del pianoπ/2 nel sistema del c.m.
