Abstract

The spectrometry of promptly emitted /spl gamma/-rays after thermal neutron capture is used for a complete, nondestructive, isotopic material analysis developed at the PTB. This method is independent of the sample dimensions and its state of aggregation. Furthermore all isotopes are detected by multi-channel analysis, simultaneously. Isotopic mass differences have been determined with an uncertainty of 10/sup -10/.
