Abstract: | It is suggested that the strength of nuclear colour van der Waals interaction, if present, can be determined by measuring
deviations from Rutherford scattering of charged hadrons from nuclei, at energies well below the Coulomb barrier. Experimental
limit on the strength of such a potential is obtained asλ<50, when the colour van der Waals potential is given byV(r)=λ(hc/r
0)(r
0/r)7, withr
0, the scaling length, taken as 1 fm. This limit is obtained from an analysis of existing experiments and by performing scattering
experiments of 3–4.6 MeV protons from a208Pb target. |
