摘要：

We analyze new QCD sum rules for the pion wave function (WF) phi(pi)(x), obtained recently in [1] in the non-local vacuum condensates method for non-diagonal correlators, and suggest a new approach for extracting WF of the pi-meson and the mass and WF of the first resonance. As a result, we obtain approximately the same form of the pion WF by two different methods and for two different ansatzes of non-local quark condensates. We predict the mass of the pi'-resonance and obtain the form of its WF.
