Abstract
A review of the most recent papers concerning the study of interatomic potentials is given. In the case of small distances, the potential values for a distance of up to 0.005a f (a f is the Firsov screening length) are obtained from a scattering experiment using proposed procedures. A new formula for the screening constant is put forward, and the influence of electron screening on cross sections for nuclear fusion reactions is described. In the range of medium internuclear distances, the experimental data on potentials agree well with the calculated ones obtained using the density functional approximation and the DMol software package for choosing the basis of wave functions. The first studies involving determination of the projectile—surface system potential from data on rainbow scattering during surface channeling are discussed.
