“…For example, if (4) holds for all sufficiently large K > O then q ( x ) = q(1xl) if q belongs to the class of potentials for which the uniqueness of the solution of the inverse scattering problem is proved for the data A (W, 8 , K) given for all e', 8, E S 2 and all K sufficiently large. These are potentials q ( x ) for which /q(x)1 s c(1 + IxJ)-~, b > 3, c = constant > 0; see [6] (for an even larger class of potentials with b > l , see [9]). …”
