Abstract: | A previously developed approach to the optimization of instrumental neutron activation analysis based on the simulation of gamma spectra of samples of the specified composition was extended to the analysis of samples of cosmic origin differing in chemical composition, including samples of small mass ( 0.01 mg) and dimensions ( 100 m). The approach was justified by comparing the results obtained with the published data. |
