利用Nachtmann矩研究了扭曲3算符对核子自旋结构函数的贡献。本文讨论了自旋结构函数g_1，g_2的Cornwall-Norton矩的靶质量修正。结果表明，修正量对从Cornwall-Norton矩中提取的扭转3d α 2的贡献起着重要作用.
The Nachtmann moment is employed to study the contribution of twist-3 operator to the nucleon spin structure functions. Target mass corrections to the Cornwall–Norton moments of the spin structure functions g1,2are discussed. It is found that the corrections play a sizeable role to the contribution of the twist-3 d˜2extracted from the Cornwall–Norton moments.
