16. Collisional losses due to nonzero impact parameters and friction are not captured in η which was measured for normal impacts on a massive plate. Averaged over all losses in translational kinetic energy due to collisions, the coefficient of restitution ≈0.8. Importantly, losses due to collisions on the Plexiglas walls are less than 5% of collisional losses even at the lowest densities considered in this paper.
