Abstract
The proton and neutron deep-inelastic scattering structure functions are found to be fit reasonably well by a finite-temperature Fermi-gas (effective) description of the confined quarks. Support problems at negative are avoided completely and formal sum rules are satisfied. The characteristic difference between the and valence distributions, which is difficult to achieve in many models of nucleon structure, arises naturally as a consequence of the different densities of and quarks in the nucleon.
