Sažetak
We present a study of the slow dynamics in the heat relaxation at very low temperature (T < 1 K) in the nominally commensurate SDW compound (TMTTF)_2Br, that we compare to the incommensurate SDW-(TMTSF)_2PF_6. Instead of a broad distribution of relaxation times g (log tau) in the PF_6 salt typical of glassy materials, the dynamics in the Br salt reveals almost "discrete bands" in the relaxation spectrum. A saturation towards equilibrium is reached very rapidly (within app. 20 mn) at T app. 100 mK in comparison with PF_6 (more than a few days for the same temperature).
