    "abstract": "Deep inelastic structure functions for the nucleon are obtained in a\nconstituent quark model on the light cone. In the Bjorken limit the parton\nmodel is derived. Structure functions from the hadronic tensor at the scale\n$\\mu \\sim 0.25$ GeV are evolved from (0.6 GeV$)^{2}$ to $-q^{2}\\sim 15$\nGeV$^{2}$. The model incorporates the quark boosts, is designed to describe\nform factors and structure functions, and to provide a link between the parton\nand constituent quark models. The main effect of the spin force between quarks\nis described in terms of smaller (and lighter) scalar $u-d$ quark pairs in the\nnucleon. To account for the negative slope of $F^{n}_{2}(x)/F^{p}_{2}(x)$,\nattraction between scalar $u-d$ quark pairs and incorporation of boosts are\nrequired. The two-body spin force between quarks from color magnetism also\nleads to a negative slope. The polarization asymmetry $A^{p}_{1}$ is in fair\nagreement with the EMC data in the valence quark region. Revised\nhep-ph/9401342, Phys. Rev. D.",
