[en] Using a colour-dependent h.o. q-q interaction, incorporating the saturation property at the 3q level and of the same strength as provides the baryonic M2 spectrum, a 6q wave function, antisymmetric with regard to both q→q and 3q→3q cluster interchanges, is constructed as an explicit solution of a 6-body Schroedinger equation. Applications to elastic and deep-inelastic e-d scattering reveal good agreement with the data without adjustable parameters
