ABSOLUTE DETERMINATION OF THE U-235/U-238 RATIO WITH AN OPTICAL INTERFEROMETER (HYPEAC)
Technical Report
·
OSTI ID:4131371
An optical method for the absolute determination of the isotope ratio of U/sup 235//U/sup 238/ is described. The recording of the homologous lines of uranium is effected by using a photoelectric Fabry-Perot interferometer (Hypeac). A series of samples of uranium oxides containing from 3 to 93% of U/sup 235/ (NBS standards) has been analyzed and the results agree to within plus or minus 0.70% with those given by the National Bureau of Standards. The relative precision of the method is of the same order, i.e., about plus or minus 1% at the 99% confidence level. (auth)
