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 dp → (pp)n has been measured at 1.75 GeV c momentum per nucleon for small transferred momenta using the one arm magnetic spectrometer STRELA at the Nuclotron accelerator. The ratio of the differential cross section of the charge exchang...

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