Interaction of strongly and weakly overlapping solitons of two independent modes is analyzed in the framework of a system of coupled nonlinear Schrödinger equations with oscillating terms. A Hamiltonian formulation is employed. Our analysis reveals that the solitons form a strongly bound state with their centers coincident and weakly bound states with their centers separated from each other.
