Abstract
We study the average density of resonances, , in a semi-infinite disordered chain coupled to a perfect lead. The function is defined in the complex energy plane and the distance from the real axes determines the resonance width. We concentrate on strong disorder and derive the asymptotic behavior of in the limit of small .
