Charge exchange dp→(pp)n reaction study at 1.75 A GeV/c by the STRELA spectrometer.

The differential cross sections of the charge exchange reaction d p → (p p) 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 d p → (p p) n to that of the n p → p n elementary process is discussed in order to estimate the spin-dependent part of the n p → p n charge exchange amplitude. The n p → p n amplitude turned out to be predominantly spin-dependent. [ABSTRACT FROM AUTHOR]
