摘要
According to the invention, the method consists in: & br / - simultaneously blowing a jet of gas on the sample (6) to be analyzed and focus a laser beam (4) on the sample to be analyzed in order to produce a plasma (12) on the surface of the sample; & br / - analyze a spectrum (s) of the light radiation emitted by the plasma; and & br / - determine, from this analysis of the spectrum, the isotopic composition of the sample.
