Inelastic pion-nucleon interactions at 7.3 GeV in emulsion

  • Published:
Il Nuovo Cimento (1955-1965)

Summary

The angular distribution of secondary pions produced in pion-nucleon collisions at 7.3 GeV was investigated. The angular distribution was found to be nearly symmetric in the π-π center-of-mass system for events of small multiplicity (n = 1, 2) and significantly asymmetric for higher multiplicities (n ≥ 3). Assuming events of small and high multiplicity to be π-π and π-core collisions, respectively, the radius of the nucleon core was estimated to be rc≤0.7-10-13 cm.

Riassunto

Si è studiata la distribuzione angolare dei pioni secondari prodotti in oollisioni pioneucleone di 7.3 GeV. Si è trovato che le distribuzioni angolari sono pressocchè simmetriche nel sistema del oentro di massa della ipotetica collisione π-π per eventi a piccola molteplicità (n = 1.2) e asimmetrici in modo rilevante per molteplioità maggiore (n = 3). Supponendo che gli eventi con molteplicità piccole e grandi siano rispettivamente collisioni π-π e π-core, c valutato il raggio del core del nucleone inr ≤0.7.10-13 cm.
