摘要: Axial channelling effects in a pyrope garnet for three zone axis orientations: [111], [211], and [311] have been investigated. The variations of the characteristic X-ray emission under [111] diffracting conditions was correlated with dynamical n-beam calculations. Site occupancies determinations obtained by comparing X + Z Y sites made using ALCHEMI techniques.
