Simulation of proton–neutron collisions in inverse kinematics and its possible application

Neutrons have played a vital role in many nuclear physics fields. In some cases, the inverse kinematics of neutrons colliding with other nuclei are also worth studying. In this study, the inverse kinematics of thermal neutrons colliding with high-energy protons is simulated by using the Monte Carlo method. Thermal neutrons are taken as target particles, whereas protons are incident particles. The simulation implies that, after collision, the energy of the output neutron at 0^∘ equals the energy of the incident proton. A possible application of the result is proposed that might yield single-energy neutrons. Some key parameters of the conceptual design were evaluated, demonstrating that the design may reach high-neutron-energy resolution.
