Measurements of the ratio R-dp of the quasi-elastic nd -} p(nn) to the elastic np -} pn charge-exchange process yields at zero proton emission angle over the 0.55-2.0 GeV neutron beam energy region

Original language description

The ratio R-dp of the quasi-elastic charge-exchange yield at the outgoing proton angle theta(p,Lab) = 0 degrees for the nd -} p(nn) reaction to the elastic np -} pn charge-exchange yield are presented. The measurements were carried at the neutron beam kinetic energies of 0.55, 0.8, 1.0, 1.2, 1.4, 1.8 and 2.0 GeV. The neutron beam was produced by break-up of primary accelerated deuterons. In the experimental set-up magnetic spectrometer with two sets of multiwire proportional chambers located upstream and downstream of the momentum analyzing magnet were used. Inelastic processes were considerably reduced by the additional detectors surrounding the hydrogen and deuterium targets. The time-of-flight system was applied to identify the detected particles. The new R-dp data are compared with the existing ones, which were obtained below 1 GeV, and with the calculations which were made using the phenomenological NN amplitude sets.
