A study of fast neutron production in p20Ne and pp interactions at 300 GeV/c

Data on the multiplicity, momentum and angular spectra of fastpn≧1 GeV/c) neutrons produced in inelastic interactions of protons with neon nuclei and protons at 300 GeV/c are presented. The experimental results obtained for p20Ne interactions are compared with predictions of the additive quark model in which the intranuclear cascading of slow particles is taken into account.
