PAULI EQUATION FOR FERMION-DYON DYNAMICS

By investigating the behaviour of a fermion moving in the field of a d yon, the generalized Dirac equation has been solved for energy eigenva lues and the Hamiltonian of this system has been shown to involve spin contribution. The generalized spin momentum of the fermion has been s hown to behave as extra energy source for fermion interacting with gen eralized electromagnetic field. The interaction of spin and orbital mo menta of fermion moving in the generalized electromagnetic field has b een analyzed. By introducing suitable spinors the Pauli equation for f ermion moving in the field of dyon has been analysed and it is shown t hat the ad hoc introduction of spin in this system perceptibly modifie s the energy eigenvalue and eigenfunction of the bound state of the sy stem.
