We are interested here in the counting function of resonances N(h) for a perturbation of a periodic Schrödinger operator P 0 by decreasing potential W (hx) (h 0). We obtain a lower bound for N(h) near some singularities of the density of states measure, associated to the unperturbed Hamiltonian P 0
