Their short coherence length, $\\xi$, places these materials in the interesting region between BCS and Bose-Einstein condensation. In the paper of F. Pistolesi and G.C. Strinati (Phys. Rev. B {\\bf 49}, 6356 (1994)), the Nozi\\`eres and Schmitt-Rink approach (NSR) is taken, which is valid for the weak coupling regime. They derive a relation between $T_{\\rm c}$ and $T_{\\rm F}$, which they insist is valid for any coupling strength.
