Experimental details are given of a thin film sectioning technique for the measurement of tracer diffusion in lithium metal. Results are given for 65 Zn in Li between 57 and 173 °C. They are expressed by D = D 0 exp ( − Q / RT ), where \documentclass{article}\pagestyle{empty}\begin{document}$ \left( {0.57\begin{array}{*{20}c} { + 0.31} \\ { - 0.20} \\ \end{array}} \right){\rm cm}^{\rm 2} {\rm /s} $\end{document} and Q = = (12.98 ± 0.24)kcal/mol. The activation energy equals, within margins of error, that of self‐diffusion in Li. The agreement between vacancy based theories and the present results appears rather doubtful.
