The energies and B(E2) transitions involving the states of the ground- and -bands in thirty transitional and deformed nuclei are calculated using the triaxial projected shell model (TPSM) approach. Systematic good agreement with the existing data substantiates the reliability of the model predictions. The Gamma-rotor version of the collective Bohr Hamiltonian is discussed in order to quantify the classification with respect to the triaxial shape degree of freedom. The pertaining criteria are applied to the TPSM results and the staggering of the energies of the -bands is analyzed in detail. An analog staggering of the intra-
is introduced for the first time. The emergence of the staggering phenomena in the transitions is explained in the terms of interactions between the bands.
