A semiclassical approach for determination of the inter-granular energy barrier height in very fine nanograins

Abstract

The new generation of hadron machines may profitably take advantage of channeling for steering and collimation of high-energy particle beams. In that case, the requirements on the quality of the crystal surface are rather stringent in terms of both lattice perfection and roughness. A new method to achieve an optimal quality of the surface is here presented. Structural and morphological characterizations show that it fulfils all needed specifications for application in hadron machines
