| 英文摘要 | The energy spectra and relative transition rates of Os-176,Os-178,Os-180 were found to be very similar to the values calculated in the framework of the critical point symmetry X(5). In order to enable more stringent tests, including also absolute transition probabilities, two coincidence RDDS lifetime measurements were performed at the Laboratori Nazionali di Legnaro with the GASP spectrometer using the (152,154)sm(Si-29,5n) Os-176,Os-171 reactions. The deduced transition quadrupole moments in Os-178 agree well with the X(5) predictions. For Os-176 only preliminary results were obtained so far. These preliminary data support an X(5) like structure also in the case of Os-176. The experimental data of both nuclei are compared to calculations in the framework of the interacting boson model (IBM) and of the general collective model (GCM). |
