Abstract
The molecular dynamics method has been used to consider manybody interactions at the channeling of the ion in a carbon nanotube, and the importance of their accounting has been shown. The effect of the wall elastic perturbation of a nanotube on a channeled particle is studied. It was confirmed that when ion with perturbation of the wall of the carbon nanotube interaction is taken into account, the ion energy loss is reduced by a factor of 1.5-3. It is shown that as the temperature of the nanotube decreases, the effect of ion interaction with wall perturbation acquires a more determinate character. Within the framework of the considered model, electronic stopping power on the electronic subsystem of a carbon nanotube is small compared to energy losses of an ion in elastic collisions on atoms of a nanotube wall.
