Abstract
The reverse of the beam polarization vector is the necessary procedure in carrying out the experiments by polarized neutrons. At the present time, a number of methods and set-ups (spin-flippers) are widely used in experiments by the thermal polarized neutrons. A new way to get the neutron beam polarization of a necessary sign during the process of neutron specular reflection from ferromagnetic anisotropic mirrors is proposed. The results of its check-up on a neutron polarized beam are given. The measured spin reverse probability by this method is near unity, and it does not practically depend on a neutron wavelength. The application of this method allows one to exclude the spin-flipper as an element of polarized neutrons set-ups.
