Abstract
This study investigates the effect of crystal electrons on the angular
distribution of channeled protons passing through a thin silicon crystal.
The effect of crystal electrons on the 2 MeV proton beam channeled through a
thin Si crystal plays an important role in the experimentally observed
angular distributions. Using the crystal rainbow effect, we have
morphologically compared the experimental and theoretical angular
distributions of channeled protons and corresponding rainbow lines, with and
without the effect of crystal electrons. Our results demonstrate that the
influence of crystal electrons affects the angular focus of the channeled
ions in the vicinity of the rainbow lines, which are the envelope of this
angular distribution. These findings provide insights into the energy loss
mechanisms for protons channeled through thin silicon crystals and can have
implications for future studies in ion beam physics.
