Measurement of the Neutron Spin Structure Function—Test of the Bjorken Sum Rule
An experiment to measure the neutron spin-dependent structure function g 1 n (x) over a range in x from 0.04 to 0.7 and with Q 2 >1 (GeV/c)2 is presented. The experiment consists of scattering a longitudinally polarized electron beam from the Stanford Linear Accelerator off a polarized 3He target and detecting scattered electrons in two magnetic spectrometers. The experiment will provide a critical test of the Bjorken sum rule and valuable information in understanding the nucleon spin structure and the violation of the Ellis-Jaffe sum rule.
