Abstract
The spectrometry of promptly emitted γ rays after thermal neutron capture is used for a complete, nondestructive, isotopic material analysis developed at the Physikalisch-Technische Bundesanstalt (PTB). This method is independent of the sample dimensions and its state of aggregation. Furthermore all isotopes are detected by multichannel analysis, simultaneously. Isotopic mass differences have been determined up to now with a relative uncertainty of 3×10-10 [1]
