  We extend our previous investigations of fermionic condensation in broad
Feshbach resonances by using the two-channel model developed for narrow
Feshbach resonances. We investigate two crossovers: the BCS-BEC crossover by
changing the s-wave scattering length and the crossover from a narrow to a
broad resonance by changing the atom-molecule coupling. At zero temperature we
analyze, as a function of both atom-molecule coupling and s-wave scattering
length, the chemical potential, the energy gap, and the condensate fraction of
atoms. In particular, we predict the contribution of Cooper pairs and preformed
molecules to the total condensate density along the two crossovers.
