    "abstract": "We consider a particle of half-integer spin which is nonrelativistic in the\nrest frame. Assuming the particle is completely polarized along third axis we\ncalculate the Bloch vector as seen by a moving observer. The result for its\nlength is expressed in terms of dispersion of some vector operator linear in\nmomentum. The relation with the localization properties is discussed.",
