Abstract：
q-deformed form of the three-parameter Wu-Zeng formula for the description of ground state bands of even-even nuclei is analyzed by taking perturbation theory into consideration. Ground state bands of the most even-even rare-earth and actinide nuclei are fitted using the damped non-linear least square fit. The results show that q-deformed three-parameter Wu-Zeng formula is more accurate than the former three-parameter Wu-Zeng formula derived from the perturbation theory. Furthermore, the new formula describes backbending phenomena much better than the previous one.
