Abstract

Analysis of the $n d \to p (nn)$ reaction in a GeV-energy region is performed in the framework based on the multiple-scattering theory for the few-nucleon system. The special kinematic condition, when momentum transfer from neutron beam to final proton closes to zero, is considered. The possibility to extract the spin-dependent term of the elementary $n p \to p n$ amplitude from $n d$ -breakup process is investigated. The energy dependence of the ratio $R = \frac{d σ _{n d}}{d Ω} / \frac{d σ _{n p}}{d Ω}$ is obtained taking account of the final-state interaction of the two outgoing neutrons in $^{1} S_{0}$ -state.
