For a Cf-252 spontaneous fission source surrounded by the polyethylene reflector, a reactor noise experiment was carried out for a non-multiplication system, using a special Transparent RUbber SheeT type Eu:LiCAF (TRUST Eu:LiCAF) detector, which is relatively small and has a high geometrical detection efficiency. By the third-order neutron correlation technique with the moving block bootstrap method, it was demonstrated that the statistically significant difference from the unique combination number "3" could be actually observed.
