Abstract：
The vibrational-rotational band structure of the collective excitation spectrum in even-even deformed nucleus was established in previous paper. In this formulation the expression of the ground band spectrum can be written approximately in a closed form of two parameters. Using this new expression the ground bands of several typical even-even deformed nuclei are analyzed systematically. The calculation is in a agreement with the experiment. The variation of the nuclear deformation with the angular momentum is discussed in some detail.
