Abstract

Thick target neutron yields produced by 7 MeV/u α incidence on a 209Bi target were measured at emission angles of 0°, 45°, and 90° using EJ301 liquid scintillators and the time-of-flight method. The experimental thick target yields were compared with those calculated using the Liège IntraNuclear-Cascade (INCL) and the JAERI Quantum Molecular Dynamics (JQMD) models followed by the Generalized Evaporation Model (GEM) implemented in PHITS. The INCL model successfully reproduced the neutron energy distribution. In contrast, the JQMD model could not reproduce the distribution, even for the reactions induced by low energy composite particles.
