THE SLOWING DOWN OF FISSION NEUTRONS IN AN INFINITE HOMOGENEOUS MEDIUM
Technical Report
·
OSTI ID:4284363
The slowing down of fast neutrons produced uniformly in an infinite non- capturing homogeneous medium with a fission spectrum energy distribution was studied. A simple approximate expression for the flux as a function of energy was obtained and found to give values in error by at most 15%. A correction to this expression is given from which values correct to a few per cent may be obtained. Numerical results for energies above 0.1 Mev are presented for hydrogen, deuterium, and carbon. For energies in the range thermal to about 0.1 Mev, the flux for all non-capturing media shows the well-known 1/E dependence. (auth)
