              			For a two-particle Schrödinger operator considered in a cell and having a
potential periodic in four variables, we establish the existence of levels
{(}i.e., eigenvalues or resonances{\rm)} in the neighborhood of singular
points of the unperturbed Green's function and derive an asymptotic formula
for these levels. We prove an existence and uniqueness theorem for the
solution of the corresponding Lippmann–Schwinger equation.
