摘要：
We report on the extraction of the Q(2)-dependence of the Bjorken sum for 0.16 < Q(2) < 1.1 GeV2. A twist analysis performed on these data shows that the higher twist corrections are small due to a cancellation between the twist-4 and 6 terms. The extraction of an effective strong coupling constant is discussed.
