Work on the interaction of oxygen with single crystal Ni-Fe alloy surfaces has been continued during the past year. Auger and LEED studies indicate the coexistence of 2-dimensional oxygen-rich and sulphur-rich phases over ranges of temperature, coverage and composition. At a total coverage of 0.5 monolayers the S-0 system seems to exhibit a eutectic type behavior. No single mechanism fits the observations on oxidation of Be over the entire range of oxide thickness studied but many features indicate that either electron tunneling or nonlinear ionic diffusion is the rate controlling step in the continuous film region. Studies of the initial stages of oxidation of Be(0001) by measurement of ellipsometric parameters indicate 3 stages in the process.
