The analytic structure of non-relativistic unitary and non-unitary S-matrices is reviewed for the cases of arbitrary interactions (and may be, with the unspecified equations of motion) inside a sphere of radius r ≤ a which pass outside it (at r > a) into the centrifugal and decreasing (exponentia...
