AbstractAbstract
[en] 1. The direct γ-spectrum for (Ir-192) was measured using spectrometer which consists of (HPGe) detector with (63 cm3) volume, spectroscopy amplifier and multichannel analyzer with (4096) channels. The energy and efficiency calibrations for the spectrometer were carried out experimentally using standard radioactive sources. 2. For the first time (γ,γ) coincidence spectra for (Ir-192) were measured using (γ,γ) fast-slow coincidence unit with Time-Amplitude convertor. The time resolution for the spectrometer was found to be (11.2 nsec.). To reduce the back-scattering ratio in coincidence spectra, two detectors one horizontal and the other vertical, were used. 3. Hight new γ-lines were detected for the first time in the direct γ-spectrum for (Ir-192). 4. The coincidence spectra were carried out at (13) selected gates. 5. Accordingly eight new γ-transitions were suggested to be added to the decay scheme of (Ir-192). 19 tabs.; 26 figs.; 38 refs
