Özet

A method for the calculation of the hadronic mixing angles using QCD sum rules is proposed. This method is then applied to predict the mixing angle between the heavy cascade hyperons Xi(Q) and Xi'Q where Q = c or Q = b. It is obtained the theta(b) = 6.4 degrees +/- 1.8 degrees and theta(c) = 5.5 degrees +/- 1.8 degrees.
