Charge exchange $$\varvec{{dp \rightarrow (pp)n}}$$ reaction study at 1.75 A GeV/c by the STRELA spectrometer

The differential cross sections of the charge exchange reaction $$dp \rightarrow (pp)n$$ has been measured at 1.75 GeV/c per nucleon for small transferred momenta using the one arm magnetic spectrometer STRELA at the Nuclotron accelerator in JINR Dubna. The ratio of the differential cross section of the charge exchange reaction $$dp \rightarrow (pp)n$$ to that of the $$np \rightarrow pn$$ elementary process is discussed in order to estimate the spin-dependent part of the $$np \rightarrow pn$$ charge exchange amplitude. The $$np \rightarrow pn$$ amplitude turned out to be predominantly spin-dependent.
