Let q ( x ) be. a real-valued function with compact support D c R3. Given the scattering amplitude A(a', a, k) for all a', a E S 2 and a fixed frequency k > 0, the moments of q(x) up to the second order are found using a computationally simple and relatively stable two-step procedure. First, one fin
