摘要: The low-lying collective spectra for an extended set of Xe nuclei are described within a phenomenological Bohr model with exactly separable potential. dependence the potential on $\ensuremath{\gamma}$ shape variable is chosen to allow description phase transition between axial and triaxial shapes, while $\ensuremath{\beta}$ excitations formalism energy-dependent potentials in order accommodate different structure excited states. combined contribution these effects leads high fidelity experimental $^{118--128}\mathrm{Xe}$ isotopes, especially rotational bands, which revealed rapid onset stable deformation $^{120}\mathrm{Xe}$ nucleus persisting also heavier isotopes. critical nature reflected its very strong state-dependence properties.
