Blakely, J. M.

An experimental research program on metal surface oxidation has been initiated. Studies of Be and of Fe-Ni single crystal surfaces are underway using the techniques of Auger and electron loss spectroscopy and low energy electron diffraction. A detailed study of the Auger line shape from clean cleaved Be (0001) planes has provided a standard against which all previous work may be composed. Progress has been made in preparing clean Be surfaces by ion sputtering techniques, computer processing of Auger data and some preliminary LEED studies have been made both of clean and oxygen covered surfaces. A liquid nitrogen cold stage for ribbon type single crystal samples has been constructed. The composition of the (100) surface of a Ni-60, Fe-40 single crystal has been in vestigated over the temperature range from 25 to 900/sup 0/C. Under uhv conditions only very slight enrichment in Fe occurs. Preliminary studies have also been made of surface structure and of C and S segregation to this Fe-Ni (100) surface.
