Interatomic Potentials at High, Medium and Low Collision Energies
A review of the latest papers in the field of the study of interatomic potentials is given. At small internuclear distances, using the proposed technique, the potential values up to distances of 0.005af (af is the Firsov screening length) are obtained from the scattering experiment. A new formula for the screening constant is proposed and the effect of electron screening on the cross sections of nuclear fusion reactions is described. In a region of medium internuclear distances, the experimental data on the potentials are in a good agreement with the calculations using the density functional approximation and the DMol software package for choosing the basis of the wave functions. The first researches of the determination of the potential of the system “incident particle-surface” from data on rainbow scattering during surface channeling are discussed.
