    "abstract": "The dynamics of wavepackets in a relativistic Dirac oscillator (DO) is\nconsidered. A comparison to nonrelativistic spin-orbit pendulum effect is\ndiscussed. Particular relativistic effects, like Zitterbewegung in spin motion,\nare found in Dirac representation. This trembling motion disappears in\nFoldy-Wouthuysen representation. A substantial difference between the dynamics\nof wavepackets corresponding to circular and linear orbits of a particle is\nobtained and discussed.",
