Abstract
We have calculated deposited energies of various energetic ions in carbon nanotubes to study nuclear point mass effects with the help of a static Monte Carlo MC simulation program As a result of nuclear point mass effects we show that at the same incident energy the iondeposited energy maximizes while its mass has intermediate mass values such as 11B 12C and 14N ion masses under hundreds keV 4He 11B 12C 14N 20Ne 28Si and 40Ar ion irradiations of a thinwalled carbon nanotube We also show that at the same incident energy the coordination defect number maximizes while its mass has an intermediate mass 20Ne value under hundreds keV 4He 20Ne and 40Ar ion irradiations of the thinwalled nanotube We derive an iondeposited energy formula to analyze these maximum phenomena and compare the MC simulation results with the MD molecular dynamics ones
