Investigation of neutron-deuteron charge-exchange reaction at small transfer momentum

Analysis of the nd → p(nn) reaction in the GeV energy region is performed in the framework based on the multiple-scattering theory for a few-nucleon system. The special kinematic condition where momentum transfer from neutron beam to final proton is close to zero is considered. The possibility of extracting the spin-dependent term of the elementary np → pn amplitude from the nd breakup process is investigated. The energy dependence of the ratio R = is obtained taking account of the finalstate interaction of the two outgoing neutrons in the ¹ S ₀ state. The text was submitted by the author in English.
