Question

The fission spectrum can be described approximately by a Maxwell distribution: χ(E)dE=CE^(1⁄2) e^((-E)⁄T) dE Where C is a constant and T a characteristic parameter equal to 2/3 of the mean energyE ̅. Using E =2MeV (~neutron energy released by fission of U-235), calculate (a) the proportion of neutrons emitted by fission above 0.8MeV, which are able possibly to induce fission of U-238. (b) The proportion of neutrons emitted above 10MeV, which are often neglected in calculations employing.
