Abstract: | Employing a Ge(Li)-NaI(Tl) detector system, gamma-gamma directional correlations for nine cascades in69Ga have been measured. The result of the present measurements combined with other existing data allowed the adoption of a 5/2? spin and parity for the 1106.4 keV level, and a 7/2? for the 1 336.1 and 1487.5 keV levels. A tentative 7/2? spin and parity has been adopted for 1923.1 keV level. Mixing ratios have been determined for six transitions. The data obtained are utilized to extractM1 andE2 reduced transition probabilities. A comparison of the experimental data is made with the predictions of the one particle-core and three particles-core coupling models. |
