Abstract
E143 at SLAC Endstation A performed deep-inelastic scattering measurements of polarized electrons from polarized protons and deuterons within cryogenic 15 NH3 and 15 ND3, respectively. Data were taken at incident energies of 29.1, 16.2 and 9.7 GeV, and covered the kinematical range x>0:03 and 0:3 <Q 2 < 12 (GeV/c) 2. The scattered electrons were detected by two spectrometers at angles of 4.5 and 7.0. From these data, the spin-dependent structure functions g p 1 (x; Q2) and g d 1 (x; Q2)were determined. This dissertation describes the experiment, with emphasis on the results on the proton spin structure. The integral of g1 over the range 0 <x<1was found to be 0:008 for the proton and d 1 p 1 =0:130 0:003 = 0:044 0:003 0:004 for the deuteron. Both values are in agreement with world data, and violate the Ellis-Ja e sum rule by more than 3 standard deviations. The neutron structure function was obtained by combining proton and deuteron results, giving n 1 From this the integral p
