Study of spectator tagging in the reaction np to pp Pi- with a deuteron beam
Study of spectator tagging in the reaction np to pp Pi- with a deuteron beam
The reaction dp --> pp pi(-) has been studied in a kinematically complete experiment at a single beam momentum pd = 1.85 GeV/c (T = 759 MeV). All four ejectiles have been detected in the large-acceptance time-of-flight spectrometer COSY-TOF. W analyzed the data along the lines of the spectator mo...

The reaction dp --> pp pi(-) has been studied in a kinematically complete experiment at a single beam momentum pd = 1.85 GeV/c (T = 759 MeV). All four ejectiles have been detected in the large-acceptance time-of-flight spectrometer COSY-TOF. W analyzed the data along the lines of the spectator model as a means to isolate the quasi-free np --> pp pi(-) reaction. The spectator proton was identified by its momentum and flight direction thus yielding access to the associated Fermi motion of the bound neutron. A comparison is carried out with Monte Carlo simulations based on two different parameterizations of the deuteron wave function. Up to a Fermi momentum of roughly 150 MeV/c no significant deviations between experimental and simulated data of various observables were found from which we conclude that the deuteron can indeed be taken as a valid substitute for the neutron. |
