Abstract
Experiments on measurements of neutron transmission function for niobium in energy region of 7-3000 keV were conducted in 1960s. Niobium used as a cover of fuel pins, him alloyed uranium and various construction steels.
In this work are present experimental data, were evaluated uncertainty of measurement values, was deducted background, were determined bounds of energy, spectra of neutrons and average total cross section. Results of evaluation of experimental and calculated data using recent libraries of nuclear data were com-pared.
The paper contains full results of experimental data for them save.
Keywords
niobium, transmission of neutron function, evaluation of experimental data, libraries of nuclear data, resonance region, calculations
