N. Lei et al., SURFACE SEGREGATION AND LAYERING IN THE LIQUID-VAPOR INTERFACE OF A DILUTE BISMUTH-GALLIUM ALLOY, The Journal of chemical physics, 104(12), 1996, pp. 4802-4805
The density distribution normal to the liquid-vapor interface of a bis
muth-gallium mixture (0.18% Bi and 99.82% Ca) has been studied by meas
urement of the x-ray reflectivity as a function of angle of incidence.
The data obtained confirm the predicted stratification of the density
distribution along the normal to the interface and the segregation of
the excess surface concentration of Bi into a monolayer atop the bulk
mixture. (C) 1996 American Institute of Physics.
