Engineering Physics Annotation << Back THE GENERALIZED DIFFUSION MODEL OF TRANSPORT AND REFLECTION FROM DIFFERENT MEDIA OF ACCELERATED ELECTRONS AND PHOTONS V.Al. NIKEROV G.V. SHOLIN The analytical model of generalized diffusion is formulated. As a result, the calculation with accuracy of 10…30 % of the average path along the coordinate of accelerated electrons and photons, as well as of the distribution of the paths and energy contribution is delivered in a wide range of particle energies for various media. The internal reflectivity of accelerated electrons and photons from different media are calculated using diagrams method in straightforward approximation. Key words: accelerated electrons, photons, generalized diffusion, straightforward approximation, internal reflectivity. Contacts: E-mail: nik@cea.ru Pp. 03-09.
