We study the simplest explicit formulas for approximate finding the complex scattering amplitude from modulus of the scattering wave function. We obtain detailed error estimates for these formulas in dimensions $d = 3$ and $d = 2$.
Keywords: Schrodinger equation, monochromatic scattering data, phase recovering, phaseless inverse scattering.
