title: Irradiation-induced confinement in a quasi-one-dimensional metal.
abstract: The anisotropic resistivity of PrBa(2)Cu(4)O(8) has been measured as a function of electron irradiation fluence. Localization effects are observed for extremely small amounts of disorder corresponding to electron mean free paths of order 100 unit cells. Estimates of the localization corrections suggest that this anomalous localization threshold heralds a crossover to a ground state with pronounced one-dimensional character in which conduction electrons become confined to a small cluster of chains.
