Channeling of protons through carbon nanotubes embedded in dielectric media
(Journal of Physics: Condensed Matter, 2008)
We investigate how the dynamic polarization of the carbon atom valence electrons affects the spatial distributions of protons channeled in (11, 9) single-wall carbon nanotubes placed in vacuum and embedded in various ...
Influence of the dynamic polarization effect on the angular distributions of protons channeled in double-wall carbon nanotubes
(Nuclear Instruments and Methods in Physics Research. Section B: Beam Interactions with Materials and Atoms, 2007)
We investigate the influence of the effect of dynamic polarization of the carbon atom valence electrons on the angular distributions of protons channeled in (6, 4)"(11, 9) double-wall carbon nanotubes. The proton velocities ...
Crystal rainbows
(Journal of Electron Spectroscopy and Related Phenomena, 2003)
This review is devoted to ion transmission through axial channels of thin crystals. In this process the rainbows occur. The effect is called the crystal rainbow effect. We shall describe its origin and present the experiments ...
Doughnuts with a 〈110〉 very thin Si crystal
(Journal of Electron Spectroscopy and Related Phenomena, 2003)
This study is devoted to the angular distributions and transmission patterns of 10 MeV protons channeled in a tilted LT 110 GT very thin Si crystal of thickness 100 nm. The tilt angle of the crystal is varied from zero up ...
Angular distributions of 1 GeV protons channeled in bent short single-wall carbon nanotubes
(Nuclear Instruments and Methods in Physics Research. Section B: Beam Interactions with Materials and Atoms, 2005)
This study is devoted to the angular distribution of protons of the energy of 1 GeV channeled in a bent short rope of (10, 10) single-wall carbon nanotubes as a function of the bending angle. The rope length was chosen to ...
Angular distributions of relativistic ions channeled in the bent 〈100〉 Si crystals
(Nuclear Instruments and Methods in Physics Research Section B: Beam Interactions with Materials and Atoms, 2002)
The angular distributions of relativistic protons channeled in the bent 〈100〉 Si crystals are considered. The ion energy is 7 TeV, the radius of curvature of the crystal is 49.8 m and the crystal thickness is varied from ...
Rainbow effect in channeling of high energy protons through single-wall carbon nanotubes
(Nuclear Instruments and Methods in Physics Research. Section B: Beam Interactions with Materials and Atoms, 2005)
We studied theoretically the angular distributions and the rainbows in the case of 1 GeV protons channeled in the ropes of (10, 10) single-wall carbon nanotubes. It was assumed that the transverse cross section of a rope ...
Rainbow effect in channeling of high energy protons in (10,0) single-wall carbon nanotubes
(Materials Science Forum, 2005)
We investigate theoretically the angular distributions and the rainbows of 1 GeV protons channeled in the ropes of (10, 0) single-wall carbon nanotubes. The rope length is varied between 0.53 and 5.29 mu m. The angular ...
Angular distributions of ions channeled in the 〈1 0 0〉 Si crystals
(Nuclear Instruments and Methods in Physics Research. Section B: Beam Interactions with Materials and Atoms, 2002)
In this study we analyze the angular distributions of Ne10+ ions channeled in the LT 100 GT Si crystals. The ion energy is 60 MeV and the crystal thickness is varied from 286 to 3435 nm. This thickness range corresponds ...
