We consider a spin-1/2 charged particle in the plane under the influence oftwo idealized Aharonov-Bohm fluxes. We show that the Pauli operator as adifferential operator is defined by appropriate boundary conditions at the twovortices. Further we explicitly construct a basis in the deficiency subspacesof the symmetric operator obtained by restricting the domain to functions withsupports separated from the vortices. This construction makes it possible toapply the Krein's formula to the Pauli operator.Comment: LaTeX source file with 3 figures, to appear in JM
