Planar positron channeling radiation on an acoustic superlattice
Planar positron channeling radiation on an acoustic superlattice
Azadegan, B.; Grigoryan, L. S.; Wagner, W.
Planar positron channeling in an acoustic superlattice and the stimulation of the emission of channeling radiation at resonance of the particle motion with the acoustic field excited in a PbTiO3 single crystal is considered in the framework of classical mechanics and electrodynamics. Based on computed particle trajectories, spectral-angular distributions of channeling radiation influenced by resonant ultrasound have been simulated. The presented method explains the influence of ultrasonic waves on the intensity of channeling radiation in a rather simple and descriptive manner.
