 Abstract: The topology of the Fermi surface of a pure transition metal can be manipulated by the formation of a random alloy with a similar metal. The giant anomaly in the helium atom inelastic scattering spectra is used to probe the alloying-induced changes in the two-dimensional Fermi surface nesting. The critical wave vector of the giant anomaly is systematically shifted for the H-saturated (110) surface of the random alloy Mo1-xRex, by varying x (0 less than or equal to x less than or equal to 0.25). Here, it is demonstrated that the giant anomaly is quite sensitive to changes in the Fermi topology induced by alloying. (C) 2001 Published by Elsevier Science B.V.
