Radioactive Decay and Measurement Techniques

The decay of Tc95m has been investigated using a scintillation spectrometer with a two-dimensional coincidence arrangement, a magnetic beta-ray spectrometer and a proportional counter. Two new gamma transitions with energies of 970 and 1630 keV were found. The analysis of the β+ spectrum yields two beta-rays with maximum energies of 700±10 keV and 492±15 keV. Relative intensities of the gamma-rays were determined by analysing the measured gamma spectra and taking into account e-γ coincidence experiments. From these data and the intensities of the conversion electrons we have calculated the internal conversion coefficients for the gamma transitions in Mo95. The decay scheme of Tc 95m is given.
