Sažetak
We present a study of the slow dynamics in the heat relaxation at very low temperature (T less than or similar to 1 K) in the nominally commensurate SDW compound (TMTTF)_2Br, that we compare to the incommensurate SDW-(TMTSF)_2PF_2. Instead of a broad distribution of relaxation times g(log tau) in the PF_6 salt, the dynamics in the Br salt reveals almost "discrete hands" 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 10 hr for the same temperature).
