UNIVERSAL DESCRIPTION OF THE O-2(-A NUCLEI() STATE IN COLLECTIVE EVEN)

A generalized description of the 0(2)(+) state in collective even-A nu clei is obtained in the e-excitation scheme. It is shown that for the whole symmetry triangle the two-e and three-e configurations are exhau sted in a sum more than 90% of the norm of the 0(2)(+) state. For the parameter range important for the description of nuclear data it is ab out 95% of the norm. The results obtained are applied to the descripti on of the E2-decay branching ratio of the 0(2)(+) State in nondeformed nuclei.
