Abstract
In a high precision experiment, Mott scattering of the Pb-208 + Pb-208 system was measured at E(lab) = 873.40 MeV and 1129.74 MeV with kinematic coincidences for angle pairs around theta(lab) = 30-degrees, 60-degrees and theta(lab) = 45-degrees, 45-degrees. The observed Mott oscillations exhibit an angular shift with respect to pure Mott scattering. A comparison with the angular shift produced by a color van der Waals force including nuclear polarizability, vacuum polarization, relativistic effects, and electronic screening provides a new upper limit for the strength of this force. Influence of atomic effects other than screening were identified for the first time.
