Abstract

An experiment to determine the low-energy parameters of np interaction in the nd breakup reaction at a neutron energy of 5 MeV of the RADEX channel of the INR RAS is proposed. The energy of the virtual 1S0 state and the np scattering length can be obtained from the experimental dependence of the reaction yield on the relative energy of motion of the “breakup” neutron and proton in the kinematic region, where the np interaction in the final state is most pronounced. The reaction events were simulated, based on which the optimal conditions for the future experiment were selected.
