Zero-degree focusing of channeled ions and crystal rainbows
(Physics Letters A, 2001)
We analyze here theoretically the connection between the effect of zero-degree focusing of channeled ions and the crystal rainbow effect. The calculations were performed for Ne10+ ions and a LT 100 GT Si thin crystal. The ...
Channeling star effect with bundles of carbon nanotubes
(Physics Letters A, 2006)
We report here about occurrence of the channeling star effect in the transmission of high energy protons through the bundles of (10. 10) single-wall carbon nanotubes, when the beam divergence is larger then the critical ...
Rainbows with a tilted 〈111〉 Si very thin crystal
(Physics Letters A, 2002)
The angular distributions of protons channeled in a tilted (111) Si very thin crystal together with the corresponding rainbow patterns are considered. The proton energy is 10 MeV while the crystal thickness is 121.1 nm, ...
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 ...
The X9 catastrophe as the organizing center of crystal rainbows
(Physics Letters A, 1993)
The crystal rainbow effect is modeled by the catastrophe theory. It is shown that the 4X9 catastrophe can be treated as the organizing center of the crystal rainbows in the cases of square, rectangular, centered rectangular ...
