Summary: In the semiclassical regime, we obtain a lower bound for the counting function of resonances corresponding to the perturbed periodic Schrödinger operator \(P(h) = -\Delta + V(x) + W(hx)\), where \(V\) is a periodic potential, \(W\) a decreasing perturbation and \(h\) a small positive constant.
