    "abstract": "Motion of a charged particle with finite size, described by Sommerfeld model,\nin static magnetic field has two peculiar features: 1.) there is the effect of\ntunneling - Sommerfeld particle overcomes the barrier and finds itself in the\nforbidden, from classical point of view, area; 2.) the untwisting of trajectory\nin cyclotron for Sommerfeld particle is strongly delayed compared to that of a\nclassical particle.",
