Correlations between neutrons with small relative momenta produced in p-Pb interactions at 7.5 GeV/ c

Correlations between neutrons with small relative momenta have been studied in p-Pb interactions at 7.5 GeV/ c. Two-neutron final-state interaction effects carrying information about spacetime characteristics of a neutron source have been observed. The source lifetime has been found to decrease with...

Description
Summary:Correlations between neutrons with small relative momenta have been studied in p-Pb interactions at 7.5 GeV/ c. Two-neutron final-state interaction effects carrying information about spacetime characteristics of a neutron source have been observed. The source lifetime has been found to decrease with increasing mean neutron kinetic energy. This fact is explained by the considerable contribution of the evaporation process to the emission of slow secondaries.
