    "abstract": "In a new application of the algebraic Interacting Vector Boson Model (IVBM),\nwe exploit the reduction of its Sp(12,R) dynamical symmetry group to Sp(4,R) x\nSO(3), which defines basis states with fixed values of the angular momentum L.\nThe relationship of the latter to $U(6) \\subset U(3)x U(2), which is the\nrotational limit of the model, means the energy distribution of collective\nstates with fixed angular momentum can be studied. Results for low-lying\nspectra of rare-earth nuclei show that the energies of collective positive\nparity states with L=0,2,4,6... lie on second order curves with respect to the\nnumber of collective phonons n or vector bosons N=4n out of which the states\nare built. The analysis of this behavior leads to insight regarding the common\nnature of collective states, tracking vibrational as well as rotational\nfeatures.",
