Backscattering/transmission of 2 MeV He++ ions quantitative correlation study
Abstract
In this work we report on detailed findings of planar channeling oscillations of 2 MeV He++ particles in (1 1 0) silicon crystal. The exact correlation and coherence mechanism between confined particles oscillating trajectories are analyzed theoretically and experimentally in backscattering/transmission geometry. Regular patterns of channeled He++ ion planar oscillations are shown to be dominated by the crystal harmonic-oscillator potential and multiple scattering effect. For the first time it was shown that under the planar channeling conditions trajectories of positively charged particles exhibit observable correlation dynamics, including the interference effect. Quantitative estimation of channeling efficiency is performed using path integral method. (C) 2015 Elsevier B.V. All rights reserved.
