摘要：
A sharp maximum in the temperature dependence of the relaxation time obtained from low-frequency permittivity measurements is found in the quasi-one-dimensional conductor (TMTTF)(2)AsF6 at a temperature of 101 K. This maximum is associated with the second-order phase transition into a charge-ordered state of Wigner type. The character of relaxation processes above and below this phase transition is discussed.
