Abstract : The penetration of matter by a heavyion beam is considered from the standpoint of the Boltzmann transport equation. It is assumed that the target may be modelled as being amorphous. This approach is worked out in detail, using the Lindhard theory for atomic collisions, and extended to include the transport properties of recoil atoms. The ultimate aim is to use the power of modern highspeed computers to numerically solve the transport equation using realistic approximations. The connection with LandauVavilov theories is examined. The solution of the transport equation near the penetrating surface is discussed; this discussion can be the basis of a selfcontained theory of surface phenomena. Some of the implications of the approach of this report, should it be successfully implemented, are mentioned. (Author)
