The efficiency of the long boron counter is calculated as a function of the incident neutron energy using the two-group model of neutron diffusion in conjunction with the age and exponential approximations for the slowing down of neutrons. The neutron energies considered are [Formula: see text]. Results are summarized graphically for several counter geometries.

The simulation of independent and cumulative yields requires precise knowledge of the initial conditions of the fission fragments immediately after scission. In this paper, we use a quantum-mechanical description of fission dynamics to extract the initial mass distribution of fission fragments for the neutron-induced fission of the two major actinides 239 Pu and 235 U, both for thermal fission and as a function of the incident neutron energy.
