我们分析磁单极子与大质量自旋一粒子的相互作用。开发了涉及矢量单极子谐波的必要角动量代数。物理上可接受的状态必然导致其差异可积的哈密顿量。虽然额外的磁矩可以导致远距离的吸引力，但没有任何磁矩值可以同时导致波函数在原点处的物理上可接受的行为。对于没有磁矩值的情况，束缚态不存在，除非引入额外的短程相互作用。
We analyze the interaction of a magnetic monopole with a massive spin-one particle. The necessary angular momentum algebra, involving vector monopole harmonics, is developed. Physically acceptable states must lead to Hamiltonians whose differences are integrable. While an extra magnetic moment can lead to attraction at large distances, no value of the magnetic moment leads simultaneously to a physically acceptable behavior of the wave function at the origin. For no value of the magnetic moment do bound states exist, unless an additional short-range interaction is introduced.
