A SPECTROGRAPHIC ABSOLUTE DETERMINATION OF THE NATURAL ABUNDANCE RATIO OF THE LITHIUM ISOTOPES
Technical Report

OSTI ID:4214770
Using separated Li/sup 7/, a study has been made of the absorption of lithium in lithium vapor. By the use of this data and theoretical considerations, the natural Li/sup 7//Li/sup 6/ ratio was found to be 12.5 plus or minus 0.3. To reduce line broadening, a new simple hollow cathode source was designed, constructed, and its memory investigated. The structure of the lithium line 6707A was resolved by a Fabry-Perot interferometer. (auth)
