Abstract. Relative transition strengths between a pair of bands in deformed nuclei can be described by Alaga rules if there is no band mixing. Deviations from the Alaga rules, for example for the transitions between the γ and the ground state bands, are often explained by bandmixing in which ZK=2 is a band mixing parameter. In this study, we have investigated transitions between the lowest K=0 band and the ground band and extracted ZK=0 band mixing parameters for some heavy nuclei. We have found that band mixing is often not adequate to explain these transition strengths.
