  High precision (p,t) studies of the deformed nucleus 158Gd allowed the
observation of 13 excited 0+ states below an excitation energy of 3.1 MeV. This
high density of low energy states, and particularly their measured B(E2)
transition strengths to the first excited 2+ state challenge nuclear models.
The pseudo SU(3) model, which successfully describes many excited bands in Dy
isotopes, is used to analyze this nuclei. We have fairly good reproduction of
most of the states but the absence of actively including nucleons occupying
intruders orbits may be the reason for the observed limitations of the model.
