Kolkhida instrument for experimental investigations of interactions of polarized neutrons with polarized nuclei

In JINR at the IBR-2 pulsed reactor [Ananiev, Blokhincev, Bulkin, et al., IET(ras.) 5 (1977) 17.] the “Kolkhida” setup intended for studies of neutron optics phenomena in interactions of polarized neutrons with polarized nuclei has been constructed. In particular, studies of nuclear precession of neutron spin in a wide energy range from thermal to neutron resonance energies are planned. The setup also makes it possible to investigate magnetic properties using polarized neutrons. given paper we present the description of the setup, its key parameters, as well as the result of computer simulation of the experiment on neutron paramagnetic resonance shift.
