The wobbling excitations in the presence of an appreciable amount of alignment are expected to appear more easily at lower angular momenta of the yrast spectra, compared with those in the textbook example. The large B(E2;I-->I-1) value for Delta(n) over cap =1 transitions where (n) over cap expresses the number of wobbling phonons is shown to be a strongly increasing function of the triaxiality parameter gamma, especially for gammagreater than or similar to+20degrees, while it is relatively independent of moments of inertia. On the other hand, the relation of the wobbling phonon energy to the total angular momentum may be used to extract quantitative information on nuclear moments of inertia. It is concluded that the gamma value of the triaxial, strongly deformed bands in Lu-163 is about equal to +20degrees and may be slightly increasing as a function of I.
