We calculate the three-body recombination rate into a shallow dimer in a gasof cold bosonic atoms near a Feshbach resonance using a two-channel contactinteraction model. The two-channel model naturally describes the variation ofthe scattering length through the Feshbach resonance and has a finite effectiverange. We confront the theory with the available experimental data and showthat the two-channel model is able to quantitatively describe the existingdata. The finite effective range leads to a reduction of the scaling factorbetween the recombination minima from the universal value of 22.7. Thereduction is larger for larger effective ranges or, correspondingly, fornarrower Feshbach resonances.
