Abstract
An Monte Carlo (MC) simulation program has been used to study ion mass dependence for the low energy channeling of natural- and pseudo-Ar ions in single-wall nanotubes. The MC simulations show that the channeling critical angle ΨC obeys the (E)−1/2 and the (M1)−1/2 rules, where E is the incident energy and M1 is the ion mass. The reason for this may be that the motion of the channeled (or de-channeled) ions should be correlated with both the incident energy E and the incident momentum (2M1E)1/2, in order to obey the conservation of energy and momentum.
