Abstract

Photoelectric methods have been applied to a spectro-isotopic technique for the analysis of isotopes of lithium utilizing the isotope shift of 0.16 angstrom. Sample time and precision have been considerably improved due to both the photoelectric method and improvements in hollow cathode and source design. At the 30 percent isotope abundance level the precision of analysis is ±0.46 percent of the lower abundance isotope.
