The Development of a Melting Method for Conversion of Zirconium Sponge to Corrosion Resistant Ingot (open access)

The Development of a Melting Method for Conversion of Zirconium Sponge to Corrosion Resistant Ingot

This report covers an investigation meant to find the feasibility of producing corrosion resistant zirconium from sponge by special melting techniques. The zirconium metal has certain required specifications, such as: the metal must be free from bafnium, and it must be free from other impurities of undesirable neutron cross section.

Part A. An X-ray Spectrometer for Use in Radioactivity Measurements, the L X-rays of Neptunium and Plutonium. Part B. Some Lighter Isotopes of Astatine (open access)

Part A. An X-ray Spectrometer for Use in Radioactivity Measurements, the L X-rays of Neptunium and Plutonium. Part B. Some Lighter Isotopes of Astatine

The following report contains two parts on the analysis of astatine, neptunium and plutonium. Part A discusses a bent crystal focusing X-ray spectrometer that has been designed and built for the observation of the X-and gamma-rays emitted in association with radioactive decay. The instrument uses proportional counter detection and is described, as well as associated electronic circuits. The plutonium L X-rays from Cm-242 and the neptunium L X-rays from Am-241 have been measures. Values of the energies and abundances are reported. Then in Part B, it discusses some isotopes of astatine hitherto unreported that have been observed in bombardments of bismuth on the University of California 184" cyclotron.
