An evaluation of average resonance parameters for niobium-93 and for natural tungsten is accomplished by utilizing the resolved resonance information in the ENDF/B files as well as the results of transmission measurements performed in the range 0.465-200keV. The possibility and the problems of the assignment of average resonance parameter sets to the mixtures of isotopes are discussed.
