Description
All the data now available for the ground rotational bands of actinide even-even nuclei and of rare-earth even-even nuclei (with bandcrossing angular momentum Ic≥16) are analyzed with the four-parameter I(I+1) expansion. The parameters obtained by the least-squares fitting definitely deviate from the relations derived from the Harris two-parameter ω2 expansion, but are closer to the relations deduced from the closed two-parameter expression by Wu and Zeng
