Abstract

The evolution of the Bjorken integral over the low Q² range of 0.17-1.10 GeV² was investigated. The Bjorken integral was extracted from inclusive scattering of polarized electrons by polarized protons, deuterons and ³He, for the region in which integral was dominated by nucleon resonances. The nonsinglet twist-4 matrix element f₂ was also extracted. It was found that that f₂^p-n was small and the total higher twist contribution was compatible with zero.
