Abstract
The variation of the dielectric constant of amorphous glycerol was measured as a function of the temperature. A logarithmic variation of Δε/ε versus T is observed between 0.5 K and 3.6 K. This gives some evidence for the existence of the two level systems in glycerol with a nearly constant density of states for energies smaller than 4 K. The coefficient of the logarithm is equal to 2.3 x 10 -4Keywords
