Earlier in the chapter we learned that the absorption cross sections of many materials exhibit a 1/v


Earlier in the chapter we erudite that the parching perverse sections of numerous materials prove a 1/v reliance on the neutron rapidity in the fiery temper stroll (underneath ~2 eV). In other tone, if σat is the value of the fiery parching perverse minority for an isotope at a fiery rapidity vt identical to 2200 m/s, demonstration that the fiery parching perverse minority at any temper underneath 2 eV is given by σa(E) = ( . 0 025 E ) ( )sat
