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.
