Abstract

Currently the analytical method used for determining the isotopic ratio of boron with a high degree of accuracy is by means of a mass spectrometer. However, the analysis by mass spectroscopy is often plagued by involved preparations, interferences, and instrument memory. It is also necessary to remove background contamination before each sample determination by "lengthy pump down periods." In some cases emission spectroscopy may yield results that are applicable for rough approximations. The absorption and activation by neutrons has been used to determine the approximate level of enrichment of the ¹⁰B isotope.
