ResumenA study of the pd -> pdη reaction in the energy range where the recent data from Uppsala are available is done in the two-step model of eta production including the final state interaction. The η-d final state interaction is incorporated through the solution of the Lippmann Schwinger equation using an elastic scattering matrix element, T-ηd->ηd, which is required to be half off-shell. It is written in a factorized form, with an off-shell form factor multiplying an on-shell part given by an effective range expansion up to the fourth power in momentum. The parameters of this expansion have been taken from an existing recent relativistic Faddeev equation solution for the ηNN system corresponding to different η-N scattering amplitudes. Calculations have also been done using few body equations within a finite rank approximation to generate T-ηd->ηd. The p-d final state interaction is included in the spirit of the Watson-Migdal prescription by multiplying the matrix element by the inverse of the Jost function. The η-d interaction is found to be dominant in the region of small invariant η-d mass, M-ηd. The p-d interaction enhances the cross section in the whole region of M-ηd, but is larger for large M-ηd. We find nearly isotropic angular distributions of the proton and the deuteron in the final state. All the above observations are in agreement with the data. The production mechanism for the entire range of the existing data on the pd -> pdη reaction seems to be dominated by the two-step model of η production.
