We consider a Hamiltonian of a system of two fermions on a three-dimensional lattice ℤ3 with special potential v^. The corresponding Shrödinger operator H(k) of the system has an invariant subspace L123−(𝕋3). We study the eigenvalues and eigenfunctions of the restriction H123−(k) of the operator H(k) in the invariant subspace L123−(𝕋3). It is shown that, all the eigenvalues of the operator H123−(k) are simple.
