Abstract

Refraction effects cause the effective 2d spacing of multilayers to vary so that the simple Bragg equation is not applicable when such devices are used for soft X-ray spectroscopy. This paper describes how the refraction term can be determined experimentally. These results compare well with dispersion and absorption terms calculated from atomic scattering factors.
