Single ion tracks
Latent damage from single-ion irradiation of a crystal(230 MeV Au into Bi2Sr2CaCuOx)
Lighter ions produce narrower tracks!

MeV ion etch pits in track detector
Heavy ion etch pit
Single MeV heavy ions are used to produce latent damage in plastic
Etching in NaOH develops this damage to produce pores
Light ions produce smaller pores
