Abstract：
The expansions of the excitation energy of the ground band in even-even deformed nucleus are discussed in the framework of our expression deduced in the previous papers. The conventional I(I+1)-expansion which is applicable to the region of low angular momenta is obtained and its radius of convergence is estimated. It can be proved that the ω₁-expansion is always convergent and hence the empirical fact that the ω_I-expansion converges better than the I(I+1)-expansion is explained satisfactorily.
