The motion of spin particles in the Schwarzschild field is examined in this paper. It is shown that Mathisson-Papapetrou equations under additional conditions\(\mathop L\limits_j {\text{ }}S^{\alpha \beta } {\text{ = }}0\), where\(\mathop L\limits_j\) is the Lie derivative of the Killing vector ξ j , permit only radial motion, motion in the equatorial plane and in the equilibrium points. All these types of motion are considered more in detail.
