Popis:	We report on the power-law dependence on temperature of the magnetic susceptibility and the specific heat of the CDW (charge density wave) system o-TaS3. All the evidences are in favor of a typical REHAC (random exchange Heisenberg antiferromagnetic chain) behaviour [I], however in the diluted limit of spins s=1/2. We propose a consistent microscopic explanation of the corresponding elementary excitations within a new state formed below the glass transition demonstrated recently in this system [2].
