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 at a temperature
of 101
. 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.
