AbstractThe density of scattering poles is shown to be proportional to the length of the convex hull of the support of the potential. In the case of a potential with finite singularities at the endpoints of the support, asymptotic formulae for the poles are given, while in the C0∞ case, an example of a potential with infinitely many scattering poles on iR is constructed. The scattering amplitude of a compactly supported potential is also characterized
