【 摘 要 】

Successful description of both positive and negative parity band configurations and their corresponding band-head's structure is obtained within the framework of the algebraic Interacting Vector Boson Model (IVBM). The analysis of the collective structure of the low lying excited states possessing different parity is carried out together with the results obtained from parabolic distributions of the energies in the space of integer and positive classification parameter (supposedly number of bosons) for large amount of even-even nuclei.
