对于自旋极化平面波通过含有均匀磁场的自旋旋转体，我们给出了详细的分析，以求解相应的薛定谔方程。得到了一个修正的自旋旋进表达式，当动能比自旋-磁场相互作用大时，该表达式简化为标准的拉莫尔旋进关系。我们表明，有实验验证制度偏离标准的拉莫尔进动公式。然后将处理扩展到自旋极化波包通过均匀磁场的情况。在不同的实验参数范围内，比较了标准拉莫尔进动公式和修正公式的计算结果。
For a spin-polarized plane wave passing through a spin-rotator containing uniform magnetic field, we provide a detailed analysis for solving the appropriate Schrödinger equation. A modified expression for spin precession is obtained which reduces to the standard Larmor precession relation when kinetic energy is very large compared to the spin-magnetic field interaction. We show that there are experimentally verifiable regimes of departure from the standard Larmor precession formula. The treatment is then extended to the case of a spin-polarized wave packet passing through a uniform magnetic field. The results based on the standard expression for Larmor precession and that obtained from the modified formula are compared in various regimes of the experimental parameters.
