L'énergie du gap Ɗ0 et des structures dans la densité d'état tunnel dues aux phonons ont été mesurées pour Cu1.8Mo6S8 à l'aide de contacts à pointe. Le rapport 2Ɗ0/kTc exède 4,0, ce qui indique un fort couplage électron-phonon. Suivant nos résultats de dérivée seconde, les vibrations optiques des atomes de Cu à basses énergie contribuent à la supraconductivité.The energy gap Ɗ0. and phonon-induced structures in the tunnelling density of states have been measured for Cu1.8Mo6S8, using point contacts. The ratio 2Ɗ0/kTc exceeds 4.0, indicating strong electron-phonon coupling. From our second derivative data we infer that the low lying optic vibrations of the Cu atoms contribute to superconductivity
