Add to ORKGIn this paper we study of the residue of the scattering amplitude for resonances near the real axis. We are motivated by the following interesting result by Lahmar-Benbernou and Martinez [Be], [BeM]. Consider the semiclassical scattering amplitude related to the Schrödinger equation in the case of a “well in an island”. They studied a simple resonance z0(h) exponentially close to the real axis, corresponding to
