  "abstract": "Solutions of the Bohr-Mottelson Hamiltonian with a sixth-order anharmonic oscillator potential, for both axially-symmetric and $γ$-unstable deformations, are applied to investigate the lowest states of the $^{94}$Zr nucleus. The experimentally observed $B_{4/2}$ anomaly is explained, within the present approach, by the presence of a coexistence between an approximately spherical shape ($2_{1}^{+}$) and an axially-symmetric deformed one ($4_{1}^{+}$). On the other hand, the energies of the $0_{2}^{+}$ and $2_{2}^{+}$ states and their associated electromagnetic transitions fit better a dynamical triaxial deformation configuration ($γ$-unstable). This overall picture of the lowest states in $^{94}$Zr corresponds to a triple shape coexistence scenario.",
