Threshold energy neutron analysis method was investigated through experiments and MCNP simulation. Experiments were carried out using DD neutron source and highly enriched uranium whose neutron energy spectrum was measured by a liquid scintillator. We confirmed availability of this method for detection of hidden special nuclear material.
