Abstract Measurement of the neutron yield is performed at a primary energy of 400 MeV/u carbons for the Pb target. Water-bath activation-foil method is used in a moderation measurement with Au foils to detect the moderated neutrons. The neutron yield is determined to be $18.4{\pm}2.1$ per carbon by integrating the neutron flux over the entire water volume. The corresponding simulation values are performed by Geant4 code with three models to compare with the experimental results. The comparison shows that the calculated result with the INCL model is in good agreement with the experimental data.
