“…In four runs of 2003-07 using the Delta-Sigma Setup at LHE JINR facility its were performed the measurements of R dp -ratio between the protons yields of quasi-elastic nd → p(nn) and elastic np → pn charge-exchange reactions when the protons are scattered under zero angle at energies T n = 0.5 ÷ 2.0 GeV [8,9,10,20,21,22]. The results of this experiment and other world data are given in Att.…”

“…Returning to the question about the representation choosing it should be noted that the first calculations of R dp -ratio which made using the solutions of nd → p(nn) and elastic np → pn charge-exchange scattering under zero. The PSA solutions VZ40 [23], FA91 [24] and SP07 [25] are taken from SAID data base as an amplitudes of np → np (θ = π) reaction and transformed to the np → pn (θ = 0) representation using (22). Values of R dp -ratio are calculated by the fromula (30).…”

It is considered the problem of spin physics related with the difference of representation of the elastic interaction between the neutron and proton. In the first case the charge-exchange reaction np → pn under the angle θ is supposed, in the second the simple elastic scattering of np → np, when the neutron is going in opposite direction π − θ. The transition from one representation to another is provided by the Majorana operator. In the framework of impulse approximation it is twice calculated the quasielastic charge-exchange reaction of a neutron on a deuteron. In the frame of nd → p(nn) scattering of proton to the angle θ it gives the well-known Dean formula. Using other representation nd → (nn)p as a neutron elastic scattering under the angle π − θ (together with neutron-spectator in nnpair) the alternative formula is presented.

The differential cross sections of the charge exchange reaction dp → ( 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 → ( 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. The np → pn amplitude turned out to be predominantly spin-dependent.
