Abstract: We consider a one-magnon system in the Heisenberg isotropic impurity model and investigate its spectrum and localized impurity states on the $\nu$-dimensional integral lattice $Z^{\nu}$. The system can have at most three localized impurity states (not counting the degeneracy multiplicities of their energies). We find the domains of these states and calculate the degeneracy multiplicities of their energies.
