We study a homogeneous Tomonaga-Luttinger liquid with backscattering potential. A perturbative computation of the conductance at and near resonance is given. We find that the backscattering of one electron dominates that of two electrons for an interaction parameter K\ensuremath\geqslant(1)/(3) and that the resonance point depends on temperature. Our results may be relevant for recent experiments on shot noise in the fractional quantum Hall effect, where the charge (1)/(3) and not (2)/(3) is measured on resonance.
