x-ray lithography using synchrotron radiation has been applied in a multi-step process for the production of plastic moulds to be used in the fabrication of separation nozzles by electrodeposition for characteristic dimensions of a few microns a total height of the nozzle structure of about 400 mum has been achieved. structural details of about 0.1 mum are being reproduced across the total thickness of the polymer layer. the surface finish of metallic separation nozzles produced by electrodeposition was equivalent to the high quality of the polymer surface. the separation-nozzle systems fabricated by the described method allow an increase by a factor three of the gas pressure in separation-nozzle plants as compared to the present standard. this results in considerable savings in the enrichment of /sup 235/u for nuclear power production
