Reflection of Light Ions from a Solid Surface: Analytical Model and Computer Simulation
Journal of Surface Investigation: X-ray, Synchrotron and Neutron Techniques(2023)
Abstract
An analytical solution to the equation for the distribution of the flux density of reflected light ions over the path length and energy losses in the target is obtained. It is based on the solution of boundary problems for the transport equation using the invariant imbedding method in the small-angle approximation. In the case of proton reflection from copper and tungsten targets, the analytical results are compared with computer-simulation data obtained using the OKSANA program, as well as with experimental data. The possibility of verifying the stopping power of the target material based on the created methodology is noted.
