摘要

The spin structure function of the neutron gj' has been determined over the range 0.03 < x < 0.6 at an average Q2 of 2 (GeV /c) 2 by measuring the asymmetry in deep inelastic scattering of polarized electrons from a polarized 3He target at energies between 19 and 26 GeV. The integral of the ueutron spiu structure function is fouud to be Jd g\'(x) dx = -0.022 ± 0.011. Earlier reported proton results t.ogether with the Bjorken sum rule predict J~ g~'(x) dx = -0.059 ± 0.019. PACS nu~1bcrs: 13.60.Hb, 29.25.Ks, ll.50.Li, l:l.88.+e
