摘要：

We show that the first moment of the spin-dependent structure function g(1)(gamma)(x, Q(2)) of a real photon vanishes independent of the momentum transfer Q(2) it is probed with. This result is non-perturbative: it holds to all orders in perturbation theory in abelian and non-abelian gauge theory and at every twist. (C) 1998 Elsevier Science B.V. All rights reserved.
