A gamma attenuation method for obtaining the density of alkali methods has been demonstrated utilizing the gamma radiation from a 137Cs source. Density data have been obtained by this method for cesium and lithium up to 1053°K. Data obtained to date for cesium are in agreement with published values; data obtained for lithium are scattered and are lower than published values.
