Observation of Many Coherent Oscillations for MeV Protons Transmitted through Stacking Faults

Abstract

The study of coherent oscillations for 2 MeV protons transmitted through stacking faults in silicon was presented. The high spatial resolution, high-contrast ion channeling measurements of stacking faults resulted in the observation of long-range coherent planar oscillations. Up to ten periodic intensity oscillations were observed over a narrow range of beam tilts to the (011) planes. The behavior was characterized by using Monte Carlo simulations and a phase-space model of planar channeled ion interactions with stacking faults.
