DEMON is a detector array for neutrons emitted in heavy ion induced re
actions at low to intermediate energies. The neutron detection efficie
ncy of some single DEMON modules has been measured in the energy range
8-21 MeV, with detection thresholds down to 0.1 MeV equivalent-electr
on (MeVee). The influence on the efficiency of cross talk, neutron-gam
ma and neutron-charged particle discrimination techniques was found to
be negligibly small. Monte Carlo simulations have been performed and
are compared with the experimental data. The relative weight of the in
teraction channel C-12(n,n'gamma) in the organic liquid scintillator w
as determined experimentally. Taking into account observed saturation
effects in the detector output, a calibration method is proposed for h
igh light outputs, based on the energy loss of cosmic ray muons.
