The author gives, in particular, asymptotic formulas for finding the scattering amplitude at fixed frequency and angles (scattered far field) from the scattering wave function given at _n_ points in dimension _d_≥ 2. These formulas are extremely explicit and their precision is proportional to _n_. The results use, in particular, the theory of Vandermonde matrices.
