New experiment arrangement to study spin rotation and oscillation of\nparticles of gas target through which beam of high energy particles passes is\ndiscussed. Such experiment arrangement make it realizable for storage ring and\nallows to study zero-angle scattering amplitude at highest possible energies.\nLife-time of particle beam in storage ring can reach several hours and even\ndays. Life-time of particle in gas target (gas trap) is long too. Particles\ncirculate in storage ring with frequency \ν of several MHz that yields to\nthe \ν-fold increase of density of high energy particles beam blowing gas\ntrap in comparison with single passing case.\n Finally, this causes perfectly acceptable angle of spin rotation of particles\ncontaining in gas cell. Relation between index of refraction and effective\npotential energy of a particle in a medium is discussed. Phenomenon of spin\nrotation of a particle captured to a trap under the action of a beam of\npolarized particles is considered. Expressions for effective potential energy\nand angle of spin rotation are derived for particles in a trap. Rrotation and\noscillation of deuteron spin is studied. Estimations for angle of rotation show\nthat the effect can be experimentally observed.\n
