Resumen:
The perturbative procedure for deformed systems which is based on the interplay between two spurious phonons with different metric is applied to the superfluid case. Good results are obtained for a well defined region in the plane labelled by the degeneracy and the deformation parameter. As byproduct, it is shown that some procedures previously used in these formalisms may yield inaccurate results.
