Abstract
Direct evidence of a new phase transition at T-CO = 100.6 K in the organic quasi-one-dimensional (TMTTF)(2)AsF6 salt has been obtained from conductivi ty and dielectric permittivity measurements. This phase transition is assig ned to a charge-ordered state (4k(F) charge density wave of Wigner type) du e to charge-induced electron-electron interactions.
