Abstract: The van der Waals force between two hadronic spherical bags is calculated, assuming that the surrounding colour ‘medium’ obeys the condition εμ = 1, ε being the colour permittivity and μ (⪢ 1) the colour permeability. The quark-gluon coupling is neglected, so that use can be made or prior electrodynamic calculations by Mitchell and Ninham (J. Chem. Phys. 56 (1972) 1117), Brevik and Skurdal (Physica A 199 (1993) 412) and others. It turns out that in the case of nucleons, at distances R ∼ 5 fm, the van der Waals force comes out in remarkably good numerical agreement with the spin-isospin-independent nucleonic force. The van der Waals interaction thus seems to be of considerable importance in the hadronic world.
