# 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 Fx,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 Sx,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 Fx,v appears outside, and both functions are unknown.
