用量子理论分析均匀磁场中带电粒子的运动

Analyzing Movement of Charged Particles in Uniform Magnetic Field with Quantum Theory

该文采用量子理论分析均匀的外磁场中带电粒子的运动情况,及相应概率流密度的计算.对于存在于原子系统的电子,由于磁矩的存在与磁场相互作用,能级发生分裂.自由运动的带电粒子,当处于均匀磁场中时,通过多种情况分析发现在垂直磁场矢势的平面内粒子做自由运动,在一固定点出现了粒子流恒定的现象,而平行矢势方向做简谐振动,粒子流恒为零.

Based on the quantum theory, this paper analyzes the movement of charged particles in external magnetic field, and the calculations of corresponding probability density flow. Due to the existence of magnetic moment, interaction with the magnetic field, the energy level of electron within the atomic system splits. When the charged particles of free movement are in a uniform magnetic field, we find that the particle moves freely in the plane of the vertical magnetic field vector potential for the electron, appeared phenomenon of a constant stream of particles in a fixed point, however, the stream of particles constant for zero when it do a harmonic vibration in the direction of parallel vector potential.
