摘要：The Dirac equation for a system of fermion and dyon is separated into decoupled ordinary differential equation in the Robertson-Walker metric. Energy levels of bound states for a fermion and a dyon with charge Z(d) < Z(d)c and for j greater-than-or-equal-to Absolute value of q + 1/2 are obtained. If dyons are indeed present in the universe, they have an interesting astronomical observation.
