Low-energy tritium ion erosion of graphite

Isotope dependence of chemical erosion of carbon

“…8b) is smaller than the Y D /Y H enhancement due to the smaller relative mass change. Our calculated Y D /Y H enhancement is in better agreement with the predictions of Liang et al [2] and Salonen et al, [9], and are consistent with the higher energy measurements of [26]. The favorable comparison between our calculations and those in [9] suggests that the enhancement factor is insensitive to whether or not the surfaces are supersaturated or whether the saturating atoms at the surfaces are of the same species as the projectile.…”

“…The measured yields decrease very rapidly in magnitude with the number of C atoms. Similar trends were found by Mech et al [35] and Macauley et al [26] at low energies and room temperature targets and by Yamada [36] at higher energies and higher target temperatures. The three C atom yields for D þ 2 and D + appear to show significant differences at the lowest investigated energy.…”
