Abstract：
The B(E2:)values and ground band energy ratio R=,are often used as indicators of the collectivity in nuclear motion.A great effort has been paid to understand systematically the relation between these quantities and the calculated deformation parameters through a standard potential energy surface approach.It is found that the B(E2:)values are dominantly determined by the equilibrium(static)deformation of nuclei.The existing NilssonstrutinskyBCS approach can reproduce nicely reasonable deformation values for a great variety of even-even nuclei, from Z=30 to actinides,while the energy ratio R reflects the whole structure of the potential energy surface,such as the stiffness and unharmonisity.
