Popis:	Matrix elements of flavor-diagonal light quark pseudoscalar densities and axial anomaly operators between vacuum and �� and ��' meson states have been determined. This has been done by evaluating current-current correlators of octet-octet and octet-singlet axial currents using QCD sum rules. The numerical values obtained for the matrix elements compare well with those obtained in the current literature. 10 pages, 12 figures, LaTex, typos added, one table replaced; to be published in Physical Review D
