Computer studies of the reflection of light ions from solids

Abstract Reflection of 10 eV to 20 keV H, T and He atoms from amorphous Al, Cu, Nb and Au has been studied using the binary collision cascade simulation program MARLOWE. The fractions of particles and energy reflected increase with increasing atomic number of the target and decrease with increasing incident energy. The peak in the energy distribution of reflected particles shifts to lower fractional energy with increasing incident energy. The number fraction reflected increases for increasing incident angle such that total reflection occurs for angles greater than a critical angle. Fair to poor agreement is found between the calculations and the experimental data available.i
