Broadband non‐selective excitation of plutonium isotopes for isotope ratio measurements in resonance ionization mass spectrometry: a theoretical study

Abstract

The isotopic bias between the resonant and off-resonant isotope under the optimized conditions was no more than 9%, which is better than an earlier reported value. These optimized laser power and bandwidth conditions are better than in the earlier experimental work since these comprehensive calculations yield simultaneous and much more accurate isotope ratios than those in the sequential and less accurate determination reported earlier. Application of these theoretical calculations to minimize the isotopic biases under these conditions for the rapid, efficient and accurate isotope ratio measurements using RIMS has been outlined.
