| Abstract: | CESR is used to measure the maximum solubility C0 and the diffusion constant D of zinc in lithium. The sample is a bimetallic layer obtained by thermal evaporation. The first deposited metal (zinc) is 300 Å thick, the second (lithium) 2μm thick. We analyze the resonance lineshape, taking into account the zinc diffusion via the Fick theorem. From the variations of the Li resonance linewidth as a function of time, we measure C0 = 50 ppm and D = 160 Å2 sec-1 at room temperature. |
