Abstract
The phenomenon of multiple production of neutrons in reactions with heavy nuclei induced by high-energy protons and light nuclei is analyzed using a Moving Source Model. The Lorentz transformation of the obtained neutron distributions is used to study the neutron characteristics in the inverse kinematics where relativistic heavy nuclei bombard a light-mass target. The neutron beam generated at 0[Formula: see text]has a Gaussian shape with a maximum at the energy of the projectile nucleons and an energy resolution [Formula: see text]/[Formula: see text] above 6 GeV.
Highlights
Experiments with beams of monoenergetic high-energy neutrons are a dream of physicists
Such neutrons cannot be produced with available accelerators, but we can generate quasi-monoenergetic neutrons in special nuclear reactions induced by accelerated protons and heavy ions
The relativistic beams of heavy Pb nuclei at SPS/CERN and Au at AGS/BNL give a new opportunity to produce a beam of quasi-monoenergetic neutrons with the highest energy, i.e. above 10 GeV, by fragmentation of heavy ions in collisions with targets of light-mass nuclei
Summary
Experiments with beams of monoenergetic high-energy neutrons are a dream of physicists. The relativistic beams of heavy Pb nuclei at SPS/CERN and Au at AGS/BNL give a new opportunity to produce a beam of quasi-monoenergetic neutrons with the highest energy, i.e. above 10 GeV, by fragmentation of heavy ions in collisions with targets of light-mass nuclei. This is a very promising feature to study neutron–proton and neutron– nucleus collisions at SPS energies. Characteristics of these ultra-relativistic neutrons are studied with the purpose of estimating the possibility of neutron beam production with available heavy ion This is an Open Access article published by World Scientific Publishing Company. The base of this work is a set of available experimental data on the neutron production in high-energy reactions and MSM analysis of these data.[5,6,7,8]
