The fast neutron spectrometer built for the investigation of nuclear reactions induced by the 14,7 MeV energy neutrons produced by a H3(d, n)He4 source is described. The zero time in the time-of-flight measurement is determined by the recoil alpha particle. This method is compared with another conventional procedure in fast neutron spectroscopy, where a pulsed neutron source is used. The usual data and - in order to illustrate the spectrometer characteristics - measured flight time spectra of the C12(n, n′) neutrons are given.
