Solid-State Reactions. A pile-loading facility for the X-10 rsactor is discribed. Experiments indicate that for pile exposures up to 15 days the resistance of Cu/sub 2/O increases monotonically and approaches a high saturation value. Bombardment of Cu/sub 2/O rectifiers has been continued. Investigations were made into the temperature dependence of rate of conductivity change for p- type germanium under bombardment. Fast neutron fluxes relative to center pile measurements were determined for hole 51 using n-type germanium plates. Two attemps were made to irradiate lithium in iron capsules using the Berkeley 60-in. cyclotron. Crystal Physics. A study was made of property changes of single crystal of Cu under irraddation. Tensile tests, electrical resistivity, and density comparisons were made between irradiated and unirradiated identical crystals. Copper samples were bombarded with protons in the Y-12 86 in. cyclotron, and effect on hardness was noted. Light-transmission characteristics of high-density glass were measured after various time exposures to a Co/sup 60/ gamma source. Remote-control equipment for use in hot cells is described. Radiation Metallurgy. Investigations were conducted on the radiation handening of copper alloys. Stress-strain curves were run on samples containing bonded strain gages both before and after irradiation. Engineering Properties. A study was made of changes in density, electrical resistance, and dimensions caused by exposure of Be in a reactor. (W.L.H.)
