Description	A recently developed algebraic version of the collective model has shown that a full range of Bohr model calculations can be executed in bases that range continuously from those of a spherical vibrator to a beta-vibrational Wilets-Jean limit. Thus, the establishment of close relationships between the algebraic structure of this model and the IBM is of special importance because one can learn from the complementary perspectives they afford. In this paper, we show by calculations that the familiar rotor-gamma vibrational spectra of the Bohr model can be obtained in the IBM by the addition of a scalar cubic in the quadrupole moment operators, of the type considered recently by Van Isacker, to an O(6) Hamiltonian. Simple fits of the low-lying spectra, electromagnetic transition rates and moments of inertia of the ground and gamma bands of Dy-162 and Er-168 are presented.

(en) Nedávno vyvinutá algebraická verze kolektivního modelu ukázala na možnost provádět výpočty v rámci Bohrova kolektivniho modelu v bázi, která spojitě probíhá od sférického vibrátoru až k beta-vibrační Wilets-Jeanove limitě. Nalezení vztahu mezi algebraickou strukturou tohoto modelu a IBM je tak obzvláště důležité, protože lze využít jejich komplementárního charakteru k získáni nových informací. V tomto článku je ukázáno, že rotačně-gamma vibrační spektra Bohrova modelu mohou být v IBM popsána pomocí skalární kubické interakce v kvadrupólových momentech. Interakce tohoto typu byla nedávno studována P. Van Isackerem. Jsou presentovány fity nizkoležících stavů, elektromagnetických přechodů a momentu setrvačnosti základního pasu a gamma pásu jader 162Dy a 168 Er. (cs)
