摘要：
Variations in isotopic abundance provide useful information for various scientific fields. Herein we performed a feasibility study by non-destructive isotopic analysis of negative muons. We irradiated two lead plate samples, one with the natural isotopic composition and one enriched with 208Pb, with negative muons and observed the gamma rays from 208Tl with a half-life of 3 min generated via muon absorption by 208Pb during muon irradiation. The isotopic abundance of 208Pb in natPb was successfully determined without sample destruction from the gamma ray intensity to be 69%, which agreed well with the mass spectrometry results.
