Rosette motion and string scattering of 20 MeV electrons in MgO single crystals
TL;DR: In this article, three distinct modes of particle motion along atomic strings were found depending on the magnitude of the transverse energy and the angular momentum L of the particle with regard to the string axis.

Bound states of swift negative particles in crystals
F. Bell,H.J. Kreiner,R. Sizmann +2 more
TL;DR: In this paper, it was shown that negative particle channeling in crystalline solids comprises a bound motion and the lifetimes of these bound states are limited by the influence of thermal lattice vibrations on the penetrating projectile.

ANISOTROPIC X-RAY EXCITATION IN ALKALI HALIDES BY 75- AND 200-keV PROTONS.
TL;DR: In this paper, the channeling behavior along alternating sequence of alkali and halide atoms was investigated by means of characteristic X-ray production, and the differences in channeling behaviour along the alternating sequence were investigated.

Argon L x-ray spectra from collisions of argon ions with various solid state targets
TL;DR: Spectral measurements have been made of Ar-L-shell X-rays produced by Ar ions incident on various solid state targets as discussed by the authors, and different spectra have been observed for targets with Z Z > 18 respectively.

Rosette motion in negative particle channelling
TL;DR: In this article, a central penetration maximum of width (0.7 ± 0.1) was achieved for 5, 10 and 15 MeV electrons along 〈100〉 in 10 μm MgO in agreement with the ψ1 Lindhard angles for the bound motion.
