Abstract
Neutron-production double-differential cross sections of iron and lead for 0.8 and 1.5 GeV protons incidences were measured in the most-forward direction. Neutrons were measured by the time-of-flight (TOF) method. An NE213 liquid organic scintillator was set at 0° as a neutron detector. Neutron detection efficiencies were obtained by calculations with a Monte Carlo simulation code SCINFUL-QMD. The present experimental data were compared with other reported experimental data and the results of calculation codes based on Intranuclear-Cascade-Evaporation (INC/E) and Quantum Molecular Dynamics (QMD) models. For neutrons associated with Δ formation, the present data deviated from predictions of these codes, and gave magnitudes between them in both 0.8 and 1.5 GeV incidences.
