Abstract: | We consider the Newton equation

((*)) |
for |j|≤2 and some α>1.
We give estimates and asymptotics for scattering solutions and scattering data for the equation (*) for the case of small
angle scattering. We show that scattering data at high energies uniquely determine theX-ray transformsPF andPv. Applying results on inversion of theX-ray transformP we obtain that ford≥2 scattering data at high energies uniquely determineF andv. For the case of potentials with compact support we give a connection between boundary value data and scattering data and
ford≥2 we obtain, using known results, a uniqueness theorem in the inverse scattering problem at fixed energy. |
