Abstrakt: We consider the two particle discrete Schrödinger operators hμλ(k); k ∈ Td, d ≥ 3 associated to the hamiltonian of a system describing a motion of two quantum particles with attractive interaction energies one site μ ≥ 0 and neighboring sites λ ≥ 0 on d-dimensional lattice Zd. The number of eigenvalues of the operator hμλ(0); 0 ∈ Td and their location are established. Moreover, sharp dependence the number of eigenvalues to the dimension of the lattice Zd is found.
