摘要：

We extend the QCD sum rule analysis of the pion electromagnetic form factor F(pi)(Q2) into the region of moderately large momentum transfers 3 less than or similar to Q2 less than or similar to 10 GeV2, where one should take into account the effects due to nonzero average virtuality of the vacuum quarks and gluons.
