Second comment on "Dense and nanometric electronic excitations induced by swift heavy ions in an ionic CaF2 crystal: Evidence for two thresholds of damage creation"

Controversy over nature and existence of the velocity effect [G. Szenes, Phys. Rev. B 87, 056101 (2013)], [M. Toulemonde et al., Phys. Rev. B 87, 056102 (2013)] reignited after new experimental data on swift heavy ion tracks in CaF2 was reported recently [M. Toulemonde et al., Phys. Rev. B 85, 054112 (2012)]. Here we show that results of the analysis in ref. [G. Szenes, Phys. Rev. B 87, 056101 (2013)] should be interpreted differently within analytical thermal spike model. We also propose explanation for apparently missing velocity effect.
