Abstract
We report the detailed non-Fermi-liquid (NFL) line shape of the dispersing excitation which defines the Fermi surface for quasi-one-dimensional Li0.9M o6O17. The properties of Li0.9Mo6O17 strongly suggest that the NFL behavior has a purely electronic origin. In relation to the theoretical Luttinger l iquid line shape, we identify significant similarities, but also important differences. [S0031-9007(99)08752-9].
