  In the framework of the semiclassical approach, we find the leading
finite-size effects on the normalized structure constants in some three-point
correlation functions in AdS_5 x S^5, expressed in terms of the conserved
string angular momenta J_1, J_2, and the worldsheet momentum p_w, identified
with the momentum p of the magnon excitations in the dual spin-chain arising in
N=4 SYM in four dimensions.
