We present first results for the transmittance, T, through a 1D disorderedsystem with an imaginary vector potential, ih, which provide a new analyticalcriterion for a delocalization transition in the model. It turns out that theposition of the critical curve on the complex energy plane (i.e. the curvewhere an exponential decay of <T> is changed by a power-law one) is differentfrom that obtained previously from the complex energy spectra. Correspondingcurves for <T^n> or <ln T> are also different. This happens because ofdifferent scales of the exponential decay of one-particle Green's functions(GF) defining the spectra and many-particle GF governing transportcharacteristics, and reflects higher-order correlations in localizedeigenstates of the non-Hermitian model.Comment: 4 pages in RevTex, 1 eps figure include
