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 quasi-elastic 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 nn-pair) the alternative formula is presented.
