The near proton drip line nucleus Pr-126 was studied via in-beam gamma-ray spectroscopy using the Ca-40 + Mo-92 reaction at 190 MeV. We observed for the first time excited states above the known isomer in this nucleus up to 31 h over bar. The observed band is discussed in the interacting boson-fermion-fermion model.The calculations and the experimental information suggest a spin 8(+) for the lowest observed state.With such a spin assignment the moment of inertia of Pr-126 gets larger than in the heavier Pr isotopes, suggesting a sudden change in deformation close to the proton drip line
