Nuclear Forces based on a Debya Layer Model for Nucleons — •Heinrich Hora — Theoret. PHysics, University of NSW, Sydney, Australia

Using the Fermi statistics for the nucleons for a generalized treatment of Debye layers, its thickness results in the three Fm depth of the surface decay of the density of nuclei if the known density of nuclei is used. This results not only in a physics explanation of the only numerically adjusted surface decay of the Woods-Saxon potential (Beiner and Bleuler, Fig. 81 of Ref.∖1∖) but also in Wigner*s particle scattering as given by the temporal Goos-Haenchen effect using total reflection at perpendicular incidence on an inhomogeneous density profile ∖2∖. Another access without the input of the nuclear density is given by comparing the Debye-surface energy with the Fermi energy of the nucleons which is equal just close to the known nuclear desity ∖3∖. At higher densities, the Fermi energy changes into the relativisitc branch explaining why nucleation is impossible in this quark-gluon soup before it at expansion reaches the known nuclear density. ∖1∖ T.
