The SPRITE and POS-SPRITE user report: An extensible calculation of positron and electron implantation in solids, BNL-64884, Informal Report, (1997). This User Report is part of a package submitted to the DOE Science and Technology Software Center. It accompanies a collection of programs developed at BNL to calculate the trajectories of positrons and electrons in solids. These programs include the calculation of scattering cross-sections relating to positron and electron energy loss and thermalization in metals and small band-gap semiconductors.
