In all cases highly oriented pyrolytic graphite was used as a testing material and dependencies of recoil effects on the crystal orientation were found but these results have, so far, not been compared. We show that the same theory can describe the results of all three experiments in a quantitative way.200810.1103/PhysRevB.78.0243012015-12-09
