Abstract
Spin-dependent asymmetries have been measured in inclusive deep-inelastic scattering of longitudinally polarized electrons by longitudinally polarized protons. Data were obtained at a scattering angle of 10\ifmmode^\circ\else\textdegree\fi{} and for incident energies of 16.2 and 22.7 GeV, which cover the kinematic range $0.18<x<0.70$ and $3.5<{Q}^{2}<10.0$ (${\mathrm{G}\mathrm{e}\mathrm{V}/\mathit{c})}^{2}$. The present results provide a test of scaling and of the Bjorken and Ellis-Jaffe sum rules and are compared with various models of proton spin structure.
