At Dalat nuclear research reactor, the gamma - gamma coincidence method is eficiently used in data nuclear research direction. By this method, some laboratories in the world test neutron activation analysis of geological, biological and environmental samples. In this paper, we present the determination of the selenium content in biological sample by gamma – gamma coincidence method. The results showed that the compton scattering was suppressed. The ratio of peak counts/back was improved up to 64.2 times. The detection limit for selenium in biological sample was enhanced to 8.9 times to compare to the method one detector system.

Different Levels

Relative K-capture probabilities to three levels of 1911r are determined from the decay of 191 Pt using the sum coincidence method based on summing of gamma rays and K X-rays in a single HPGe detector. The results agree with theoretical values. The electron-capture decay energy calculated using j3-decay properties to different levels belonging to the same rotational family is in agreement with the experimental value.
