Abstract
We report experiments on resonant tunneling of charge e/3 quasiparticles through states bound on a quantum antidot. We find that at a given temperature T the line shape of resonances fits predictions of Fermi and Luttinger liquid theories equally well, the difference between the theoretical line shapes being well within 1%. As T is varied, the experimental resonances scale linearly with T, as expected for both Fermi and Luttinger tunneling for quasiparticles, and not as predicted by the Luttinger theory for electrons.
