Abstract
Using the technique of Cherniak and Zhitnitzky we have calculated the wavefunctions of {rho}(770) and {Phi}(1020) within the framework of QCD sum rules. Whereas the standard approach assumes light-like distances of the quarks (z{sup 2} = 0), we also have taken into account higher order terms in z{sup 2}. Thus, we obtained non-vanishing orbital angular momentum contributions. The first few moments of various invariant functions have been calculated with the help of an especially developed REDUCE program package. In zeroth order (z{sup 2} = 0) our results of the reconstructed wavefunctions agree with those in the literature. However, we got first order contributions in z{sup 2} of an amount of almost 10% of the corresponding zeroth order. (orig.).
