Abstract

Atomic beam splitter needs for the practical realization of nano-scale lithography by coherent scattering of the atoms. We consider the different types of atomic beam splitters, which could be used for the creation of the space structures with nano-scale period. We concentrate to a few main schemes of an interaction between an atom beam and optical radiation, which can produce a large angle splitting of atom beam into only two main momentum components: multi Bragg scattering an atom wave packet in standing wave; coherent splitting by scattering of an atom wave packet in standing wave with modulated intensity, when the intensity of the standing wave changes harmonically.
