    The determination of neutron spectra by means of differential spectrometry techniques is a powerful tool to check and evaluate nuclear data. But to reach this objective it is of primary importance to define the confidence that may be attributed to the spectral results wearing errors and uncertainties related to many parameters, such as cross-sections of the reaction used, detection equipment and unfolding codes.
    Though only an intercomparison on a large scale can give a valuable estimation of the uncertainties, the differential neutron spectrometry techniques of KEK, RCN and C.E.N./S.C.K., i.e. (n,p), He(n,p)t and *Li(n,a)t were intercompared in the MOL EE fast assembly.
    With the care and the precautions taken in the present work and under the experimental conditions described, an agreement of ± 5 % is generally found between 0.02 and 4 MeV,vconsequently the same confidence can stand for the neutron spectra measured in similar nuclear and experimental conditions.
