Determination of x-ray reflection phases using N-beam diffraction

[[abstract]]The relationship between X-ray reflection phase and N-beam diffraction as well as the phase-determination method utilizing N-beam interference effects are described. The experimental techniques of producing N-beam diffraction and the theoretical grounds, bath kinematical and dynamical, of the phase-determination method are presented and discussed. Experimental phase determination using N-beam diffraction for single crystals of small molecules and macromolecules is demonstrated. Prospective future development of this particular phasing method is also given.[[fileno]]2010105010002[[department]]物理
