Abstract
The deep-inelastic scattering structure function ratio F-2(n)/F-2(p) a nd the nucleon spin asymmetries are found to be strongly x-dependent. In the context of the parton model, the observed inhomogeneities mean that quarks with different flavors and spins carry different fractions of the nucleon momentum. We show that all of these asymmetry effects can be qualitatively understood in terms of the admixtures of excited- state configurations in the nucleon wave function due to color hyperfi ne interactions.
