ON SOLUTION OF THE KINETIC EQUATION FOR TRANSFER OF NEUTRONS OR GAMMA QUANTA BY THE PARTIAL PROBABILITY METHOD (in Russian)
Solution of the kinetic equation for slowing down or diffusion of neutrons and propagation of gamma quanta is reduced to the simpler problem of multiple integration. An exact solution of the kinetic equation (stationary as well as nonstationary) is found in the form of a sum the with term of which is approximately a 3x-fold integral. The latter has the meaning of the transition probability of a particle from one point in its phase space to another after x collisions. In the particular case of slowing down and diffusion of neutrons with a constant mean free path, it is shown that this exact solution, which depends on all six variables (three space coondinates and three momentum projections) can be reduced to simple quadratures and sums.
