Abstract
The electron self-energy due to the scattering on nonmagnetic impurities in a spin-charge separated non-Fermi liquid is calculated. The frequency depe ndence of the inverse scattering time is proportional to omega, for the cas e when the anomalous parameter alpha = 0, and to omega(1+alpha) for alpha n ot equal 0. The scattering time is cutoff dependent when the anomalous para meter oc is nonzero.
