Physical and Inorganic Chemistry. Research and development were continued on the six-inch and fourinch series of ion-exchange columns, and nearly ideal conditions were determined for use in resolving Lu, Yb, Tm, Er, and Ho mixtures after a preliminary separation from Y and light rare earths with ethylenediaminetetraacetic acid (EDTA). An ion-exchange process for separating Y, Mg, and Ca is being investigated. The work on the heat capacity of Lu has been completed. Magnetic moment studies of Er metal were completed. Work on the heat capacity of Tb is presented. Results of ailoy studies of Y with some common metals are presented. Pyrometallurgy. A study of the separation of fission products from U by the process of pouring the molten fuel through a packed column of graphite or refractory oxide is presented. Analytical Chemistry. An investigation was started for a suitable analytical method for the determination of HF in the atmosphere. A procedure for tbe determination of oxygen in metals and metal fluorides is presented. Spectrochemistry. The emission spectrometric techniques for the determination of O/sub 2/ in metals have been extended to the determination of O/sub 2/ in Zr and Y metal. A flame spectrometric method for the determination of La in all combirntions of rare earth mixtures has been developed. Radiochemistry. The isotope Sb/sup 127/ is produced in fission and has been studied as one of the fission products of U. Study of the recoil chemistry of carbon in organic compounds as initiated by the C/sup 12/( gamma ,n)Cl/sup 11/ reaction, followed by separation of the compounds by gas chromatography, was continued. X-Ray Chemistry. The influence of the crystal versus the local field in determining the structure of complex ions of transition metals has been studied. (For preceding period see ISC-902.) (W.L.H.)
