  The observed properties of the low-lying collective states of $^{96}$Zr are
investigated within the geometrical collective model. The quadrupole-collective
Bohr Hamiltonian with the potential having spherical and axially-symmetric
deformed minima is applied. The role of triaxiality is investigated by rotating
the potential in $\gamma$-degree of freedom so that the deformed minimum occurs
at various axially asymmetric shapes. The change of excitation energies and
reduced matrix elements of quadrupole transitions with increase of triaxiliaty
is analyzed.
