“…Trigger Ti was sensitive to muons scattered at angles larger than 10 mrad and the small angle trigger T2 selected muons at angles between 3 and 15 mrad. The triggers were formed using fast coincidence matrices [13] which required combinations of strips from the hodoscopes Hi, H3 and H4 for Ti (Hi', H3' and H4' for T2) such that the triggering particle was required to come from the target region. Combinations of strips which were mainly populated by radiative events were inhibited.…”

Results are presented on the ratio of neutron and proton structure functions, F~'/F~, deduced from deep inelastic scattering of muons from hydrogen and deuterium. The data, which were obtained at the CERN muon beam at 90 and 280 GeV incident energy, cover the kinematic range x = 0.002-0.80 and Q2 = 0.1-190 GeV2. The measured structure function ratios have small statistical and systematic errors, particularly at small and intermediate x. The observed Q2 dependence in the range x = 0.1-0.4 is stronger than predicted by perturbative QCD. From the present data together with results from other experiments it is suggested that the twist-four coefficient for the proton is smaller than that for the neutron for x larger than 0.2.

“…The proton polarization was measured with nuclear magnetic resonance techniques, and varied between 70% and 80%. The scattered muons were measured with a large-aperture, high-resolution magnetic spectrometer (64), using large arrays of scintillation counters for triggering and different types of wire chambers for track reconstruction. The layout of this spectrometer is very similar to the one used by the Spin Muon Collaboration (SMC) experiment, which is discussed in more detail below.…”

Key Words proton spin, deep inelastic scattering, quark-parton model, sum rules, quantum chromodynamics s Abstract We review the study of the internal spin structure of the proton and neutron. High-energy scattering of polarized leptons by polarized protons, neutrons, and deuterons provides a measurement of the nucleon spin structure functions. These structure functions give information on the polarized quark contributions to the spin of the proton and the neutron and allow tests of the quark-parton model and quantum chromodynamics. We discuss the formalism of deep inelastic scattering of polarized leptons on polarized nucleons, the past decade of experimental progress, and future programs to measure the polarized gluon contribution to the proton spin.
