Abstract

The neutron total transmissions and self-indication functions for the natural Nb, Mo and Pb have been measured at the 1006 m flight path of the IBR-30 by means of the 4p-geometry detector with the 3He counters. The metallic disks of different thickness and 80 mm diameter of Nb, Mo and Pb have been used as samples-filters for measurement of transmission functions. The group cross-sections and their self-shielding factors have been obtained from the ones in the energy range 0.100 - 200 keV. The experimental uncertainties of group cross sections and their self-shielding factors are 2-10%. Analogous values were calculated by the program GRUCON with the use of the BROND-2,ENDF/B-6.7, JENDL-3.2 and JEF-2.2 evaluated data libraries.
