Rainbows in transmission of high energy protons through carbon nanotubes
(European Physical Journal B. Condensed Matter and Complex Systems, 2005)
We investigate theoretically the angular distribution and the rainbows in the case of 1 GeV protons transmitted through the 1 mu m long rope of ( 10, 10) single-wall carbon nanotubes. The angular distribution of transmitted ...
Proton channeling through long chiral carbon nanotubes: The rainbow route to equilibration
(Physics Letters A, 2008)
In this work we investigate the rainbows appearing in channeling of 1 GeV protons through the long (11, 9) single-wall carbon nanotubes. The nanotube length is varied from 10 to 500 pm. The angular distributions of channeled ...
Angular distributions of high energy protons channeled in long (10,10) single-wall carbon nanotubes
(Nuclear Instruments and Methods in Physics Research. Section B: Beam Interactions with Materials and Atoms, 2009)
In this work we study the angular distributions of 1 GeV protons channeled in long (10,10) single-wall carbon nanotubes. The nanotube length, L, is varied between 10 and 100 mu m. The angular distributions of channeled ...
Probing high-energy ion-implanted silicon by micro-Raman spectroscopy
(Journal of Raman Spectroscopy, 2014)
The effect of ion implantation (4MeV(12)C(2+), 5MeV(16)O(2+), and 8MeV(28)Si(2+)) on [110] silicon wafers in channeling and random orientation is investigated by micro-Raman spectroscopy. The profiles were measured using ...
Depth profiling of high energy nitrogen ions implanted in the (100), (110) and randomly oriented silicon crystals
(Nuclear Instruments and Methods in Physics Research. Section B: Beam Interactions with Materials and Atoms, 2012)
This work reports on the experimentally obtained depth profiles of 4 MeV N-14(2+) ions implanted in the (100), (110) and randomly oriented silicon crystals. The ion fluence was 10(17) particles/cm(2), The nitrogen depth ...
Superfocusing of channeled protons and crystal rainbows
(Nuclear Instruments and Methods in Physics Research. Section B: Beam Interactions with Materials and Atoms, 2009)
This study is devoted to the effect of superfocusing of protons having the energy of 2 MeV in a LT 1 0 0 GT channel of a Si crystal. The analysis is performed by the theory of crystal rainbows. We analyze the superfocusing ...
Gompertz type dechanneling functions for protons in 〈1 0 0〉, 〈1 1 0〉 and 〈1 1 1〉 Si crystal channels
(Nuclear Instruments and Methods in Physics Research. Section B: Beam Interactions with Materials and Atoms, 2007)
In this work the energy dependences of the Gompertz type sigmoidal dechanneling function parameters for protons in LT 1 0 0 GT , LT 1 1 0 GT and LT 1 1 1 GT Si crystal channels is investigated theoretically. The proton ...
Investigation of the graphene thermal motion by rainbow scattering
(Carbon, 2019)
The thermal motion of graphene atoms was investigated using angular distributions of transmitted protons. The static proton-graphene interaction potential was constructed applying the Doyle-Turner's expression for the ...

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 ...
