Abstract
Nuclear resonance fluorescence excited with continuous electron bremsstrahlung from the 4.3 MV Stuttgart Dynamitron accelerator is used as a nondestructive method to determine the content of bulk isotopic diamonds The smallest detectable amount of in carbon or low matrices is on the order of 0.5 mg. The relative accuracy of absolute mass determinations is about Errors are mainly due to uncertainties in the natural widths Γ of the nuclear levels at 3089 and 3684 keV used in the measurements. The results confirm a previous calibration which is based on Raman scattering and the destructive determination of by mass spectroscopy.
