isotopic ratios were measured in the presence of high levels of using Resonance Ionization Mass Spectrometry (RIMS). Single- and double-resonance excitation of Cs with high-resolution continuous-wave (cw) lasers along and pathways were followed by photoionization with an Ar ion laser. The age of a standard burn-up sample was determined using RIMS and compared to Thermal Ionization Mass Spectrometry (TIMS). The efficiency, selectivity and isobar suppression for TIMS and RIMS has been compared. The overall RIMS efficiency was found to be with a combined selectivity of for both and against using the preferred single-resonance excitation scheme.
