- Abstract
Toothacker, Preuss and Bugenis have photographically recorded1 diffraction lines from a single lithium fluoride crystal and lithium fluoride powder using Mn characteristic X-ray spectra emitted by 55Fe. They have criticized our sources produced by the neutron irradiation of the stable 54Fe in a nuclear reactor. They state that such sources are contaminated with 59Fe and 54Mn, tho gamma rays of which present a film fogging problem. We have not found this to be so. At the Seventh International Congress on Crystallography in Moscow (July 1966) we reported experiments with carefully purified 55Fe sources. (It appears that the original paper has been omitted from the report on the Moscow conference.) The amount of quanta of the hard gamma-radiation emitted by 54Mn and 59Fe isotopes in our sources did not exceed 10−6 of the amount of quanta of Mn characteristic X-ray radiation2.
