Assessing electronic energy loss of heavy ions detected in reflection geometry

We study energy loss spectra of bromine ions scattered from silver thin films in the range 4 to 36 MeV forward reflection geometry. The different contributions are analyzed by complementary Monte Carlo simulations. assess dependence scattering yield and nuclear electronic losses on penetration depth detected ions. For larger depth, we observe decreased elastic increased trajectory length comparison with predictions single scattering, increasing effects for lower energies. To investigate entanglement information, stopping cross sections deduced experimental two approaches: (a) assuming a model (b) making use data obtained approaches compared, relative effect multiple length. Results both methods discussed context composition profiling compared literature Stopping Range Ions Matter (SRIM) resulting good agreement.
