Abstract
Mott scattering of the {sup 208}Pb+{sup 208}Pb system was measured with kinematic coincidences at energies below the Coulomb barrier. The oscillations observed at E{sub lab}=873.40 and 1129.74 MeV exhibit an angular shift with respect to pure Mott scattering. Theoretical estimates including the nuclear polarizability of target and projectile, vacuum polarization, relativistic effects and electronic screening underestimate the angular shifts. The comparison of the angular shift produced by a colour Van der Waals force folded into the nuclear matter distributions of the target and projectile allows the determination of a new upper limit for the strength of this force.
