  We have measured double-differential cross sections in the interaction of 175
MeV quasimonoenergetic neutrons with O, Si, Fe and Bi. We have compared these
results with model calculations with INCL4.5-Abla07, MCNP6 and TALYS-1.2. We
have also compared our data with PHITS calculations, where the pre-equilibrium
stage of the reaction was accounted respectively using the JENDL/HE-2007
evaluated data library, the quantum molecular dynamics model (QMD) and a
modified version of QMD (MQMD) to include a surface coalescence model. The most
crucial aspect is the formation and emission of composite particles in the
pre-equilibrium stage.
