A nuclear monochromator using grazing incidence anti-reflection (GIAR) films of {sup 119}SnO{sub 2} coated on a Pd backing mirror was designed, fabricated and characterized. {sup 119}SnO{sub 2} /Pd/quartz GIAR films were synthesized by a magnetron reactive sputtering technique. The films were characterized by x-ray scattering of 23.87 keV synchrotron radiation source. From the measurement of off-resonance reflectivity and the simulation of the resonant nuclear reflectivity, {approximately} 0.8 reflectivity with 10{sup {minus}2} electronic reflectivity and an energy band width {approximately} 100{Gamma} where {Gamma} is a natural line width, at a 2 mrad incident beam angle would be expected. The requirements and alternative methods to improve performance of a GIAR film nuclear monochromator were discussed.
