Description
Summary:•For the first time we presented theoretically obtained distributions of channeled protons with radially deformed SWNT.•Our findings indicate that influence of the radial deformation is very strong and it should not be omitted in simulations.•We show that the spatial and angular distributions depend strongly of level of radial deformation of nanotube.•Our obtained results can be compared with measured distributions to reveal the presence of various types of defects in SWNT. In this paper we have presented a theoretical investigation of the channeling of 1 GeV protons with the radial deformed (10, 0) single-wall carbon nanotubes (SWNTs). We have calculated channeling potential within the deformed nanotubes. For the first time we presented theoretically obtained spatial and angular distributions of channeled protons with radially deformed SWNT. We used a Monte Carlo (MC) simulation technique. We show that the spatial and angular distributions depend strongly of level of radial deformation of nanotube. These results may be useful for nanotube characterization and production and guiding of nanosized ion beams.
