1. V. A. Matveev and P. Sorba, Lett, al Nuovo 20, 435 (1977). They estmate that perhaps 5.6% of the deuteron wave function is “hidden color”, i.e. exotic arrangements of the six quarks. I thank S. Brodsky for focussing my attention on such posibilities. See his talk in this confernce.
2. There are many calculations which purport to show that the meson exchange forces produce A n states. See for example the review by E. L. Lomon, “Two Hadron Interaction”, Proceedings of the 1978 Graz conference on Few Body Systems and Nuclear Forces II (Springer Verlag, 1978) eds. H. Zingl, M. Haftel and H. Zankel, p.48.
3. The first 6 quark calculation was by R. L. Jaffe, Phys. Rev. Lett. 38, 195 (1977); Errata 38, 617 (1977). Later calculations include “tfibse of A. Th. M. Aerts, P. T. G. Mulders, and T. T. de Swart, Phys. Rev. D17, 260 (1978).v
