The electron spectrum in the energy range of 575 to 675 keV from the decay of I132 was studied by means of an ion-free spectrometer. Internal conversion lines corresponding to transitions of 522±1, 630.4±0.7, 672±2, 667.7±0.5 and 652±4 (tentatively established) keV were recorded. The last four transitions have not been resolved from each other before. The K-conversion coefficient of the 668-keV transition was measured by the internal-external method to be (3.3±0.9) × 10−3. This value agrees, within the large limits of error, with the theoretical E2 conversion coefficient value calculated by Rose. |
