Sometimes ultrane cross section libraries use different values for the width of the energy groups in


Sometimes ultrane peevish minority libraries use different values for the width of the soul clumps in the clash soul stroll. Suppose that three continuous soul clumps in an ultrane peevish minority library possess parching peevish minoritys of 10, 30, and 12 barns in the clash soul stroll. If the rst clump is 10 eV extensive, the cooperate clump is 20 eV extensive, and the third clump is 10 eV extensive, and the clumps are defenseless to a neutron ux of 2 × 108 neutrons/cm2/s, 1 × 108 neutrons/cm2/s, and 2 × 108 neutrons/cm2/s, respectively, what is the parching peevish minority for the closed soul group? What corporeal “entity” does the convenient soul clump in the ultrane peevish minority library most likely hold?
