AbstractAbstract
[en] Considerable effort has been directed toward seeking an optimal spatial differencing scheme for the neutron transport equation. This search led to a best scheme (using specific criteria to define ''best''): the linear characteristic method. However, we have recently considered radiative transfer problems in which the same problem may have both optically thick and optically thin regions, with the maximum optical thicknesses being much greater than those generally encountered in neutron transport problems. Here, we describe the important features of these radiative transfer problems and a new differencing scheme which seems to have advantages for radiative transfer calculations relative to the older schemes

AbstractAbstract
[en] The temperature--density equation of Kinetic Theory and the conservative neutron transport equation are studied. In both cases a modified version of the Larsen--Habetler resolvent integration technique is applied to obtain full-range and half-range expansions. For the neutron transport equation the method applied is seen to have notational advantages over previous approaches. In the case of the temperature--density equation this development extends previous results by enlarging the class of expandable functions, and has the added advantage of rigor and simplicity. As a natural extension of the kinetic theory results, an integral equation for the surface density is derived for half-space problems involving the boundary condition of arbitrary accommodation

AbstractAbstract
[en] The Fokker-Planck equation describing a beam of charged particles entering a homogeneous medium is solved here for a stationary case. Interactions are taken into account through Coulomb cross-section. Starting from the charged-particle distribution as a function of velocity and penetration depth, some important kinetic quantities are calculated, like mean velocity, range and the loss of energy per unit space. In such quantities the energy straggling is taken into account. This phenomenon is not considered in the continuous slowing-down approximation that is commonly used to obtain the range and the stopping power. Finally the well-know Bohr of Bethe formula is found as a first-order approximation of the Fokker-Planck equation
