  The deformation properties of 74Ge, 74Se and 74Kr are studied within the
phenomenological Bohr-Mottelson model, having as input the experimental
collective energy states, as well with Covariant Density Functional theories
based on microscopic structural information. The results of these approaches
are shown to be compatible in what concerns the presence of coexisting shapes
in the considered nuclei, while the emergence of shape mixing is deduced from
the phenomenological calculated collective states.
