Rainbows in Channeling of 1 GeV Protons in a Bent Very Short (11,9) Single-wall Carbon Nanotube
(International Journal of Nonlinear Sciences and Numerical Simulation, 2010)
In this work we investigate theoretically the spatial and angular distributions of protons channeled in a bent very short (11, 9) single-wall carbon nanotube. The initial proton kinetic energy is 1 GeV and the nanotube ...
Proton-silicon interaction potential extracted from high-resolution measurements of crystal rainbows
(Nuclear Instruments and Methods in Physics Research. Section B: Beam Interactions with Materials and Atoms, 2015)
This study provides a way to produce very accurate ion atom interaction potentials. We present the high-resolution measurements of angular distributions of protons of energies between 2.0 and 0.7 MeV channeled in a 55 nm ...
Superfocusing and zero-degree focusing in planar channeling of protons in a thin silicon crystal
(Nuclear Instruments and Methods in Physics Research. Section B: Beam Interactions with Materials and Atoms, 2019)
This is a theoretical study of the superfocusing and zero-degree focusing effects appearing in channeling of protons of energy of 2 MeV in the {1 1 0} channel of a thin silicon crystal. We prove that the ultimate origin ...
Crystal rainbow channeling potential for 〈1 0 0〉 and 〈1 1 1〉 cubic crystallographic crystals
(Nuclear Instruments and Methods in Physics Research, Section B: Beam Interactions with Materials and Atoms, 2021)
In this work we show a way how the crystal rainbow channeling effect can be applied for obtaining the interaction potential between 2 MeV protons and the cubic crystallographic crystals, in the cases of axial channeling ...
Universal axial (0 0 1) rainbow channeling interaction potential
(Nuclear Instruments and Methods in Physics Research Section B: Beam Interactions with Materials and Atoms, 2019)
This work is devoted to the construction of the universal axial (0 0 1) rainbow channeling proton-crystal interaction potential. It has been done by modifying the Moliere's interaction potential. We show that for very thin ...
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 ...
