Classical scattering in strongly attractive potentials

Understand

Scattering in central attractive potentials is investigated systematically, in the limit of strong interaction, when large-angles scattering dominates.

• In particular, three important model interactions (Lennard-Jones, Yukawa, and exponential), which are qualitatively different from each other, are studied in detail.
• It is shown that for each of these interactions the dependence of the scattering angle on the properly normalized impact parameter exhibits a quasi-universal behavior.
• This implies simple scaling of the transport cross sections with energy in the considered limit.
