Abstract

It is possible to write the Boltzmann equation as an integral equation whenever the scattering and the source are isotropic. To do this we return to equation 1-50 (report M-3336) in which F(x,v,mu) is expressed as an integral over F sub o and S, the source distribution. Since we assume S is isotropic, we may put S(x,v,mu) = S sub o (x,v) /2: where S sub o is the total number of neutrons produced per cu cm per second. As it stands equation 1-50 is not quite an integral equation because the total F(x,v) appears outside, and both functions are unknown.
