Abstract
Isotopic ratio measurements of 135Cs to 137Cs were performed using Resonance Ionization Mass Spectrometry (RIMS) to determine the chronological age of nuclear fuel burn-up samples. Initial measurements on a lake sediment sample are being performed at NIST for determination of cesium content in the sample. Single-resonance excitation 6s 2S1/2 (F = 4) → 6p 2P3/2 (F = 5) with an extended cavity diode laser followed by photoionization with the 488 nm line of an argon ion laser yielded optical selectivity for 135Cs and 137Cs of more than 2 orders of magnitude against stable 133Cs and overall selectivity of 108. An overall efficiency of 5×10−7was measured for standard 133Cs solutions and for the nuclear fuel burn-up samples. Selectivity and efficiency measurements were also performed using the 6s → 8s two photon transition.
