An interferometric isotopic assay for lithium with the line lambda = 4603 (2P --4D) is described. The light source is a liquid nitrogen-cooled hollow cathode working under low current. Excited in this way, the line lambda = 4603 does not show any self absorption, unlike the red line lambda = 6707.8 A. It is shown that the Doppler width is different for both isotopes of lithium. The value of the natural abundance ratio of lithium isotopes is found to be 12.5 plus or minus 0.3. (auth)
