Abstract
A deconvolution procedure is proposed to determine the resonant width Gamma, the asymmetry parameter q, and the background cross section sig ma(b) of a Fano-type resonance in the absence. of an:ultrahigh-energy resolution. This procedure enables a direct extrapolation to infinite energy resolution using a set of: explicit analytical relations in ter ms of the ratio between the width Gamma and the experimental energy re solution Omega in the limit of Gamma/Omega much less than 1.
