The picosecond pulse of quasi-monoenergetic high-energy neutrons is produced in each interaction of relativistic heavy nuclei in light target. The energy and angular distributions of the neutrons for Pb + 1H and Pb + C collisions are estimated using Lorentz transformation of a Moving Source Model fit to the neutron data for reactions p + Pb and C + Pb at GeV energies. The analysis of neutron characteristics and energy resolution as a function of beam energy is given. This phenomenon may be used for generation of neutron beam at SPS energies at CERN and also it leads to formation of parasitic neutron beam in interactions of heavy ions with beam line materials. The last effect must be taken into account in a design of accelerator beam lines and shielding, experimental setups and forward detectors.
