【 摘 要 】

The present paper theoretically studies helium and helion passage through pores in a graphene sheet using classical molecular dynamics. It was found that, within the frame of the suggested model, for considerably large pores with the diameter of 0.75 nm, helium permeates much better than helion, which is quite an unexpected result in itself.
