摘要: The interacting boson approximation has been applied to the deformed nucleus $^{168}\mathrm{Er}$. parametrization used corresponds a description close SU(3) limit of model. calculation, which is most detailed test date, correctly reproduces complete sequence positive-parity collective bands below pairing gap and provides an excellent overall their decay properties.
