为了在大变形区识别双{gamma}振动态，我们对{sup 168}Er进行了库仑激发实验。我们可以观察到1235 keV和962 keV {gamma}跃迁从2056 keV 4{sup +}态衰减。测得的{italE}2跃迁几率支持4{sup +}态作为双声子{gamma}振动态的分配。
In order to identify double-{gamma} vibrational states in well-deformed regions, we have made a Coulomb excitation experiment for {sup 168}Er. We could observe 1235-keV and 962-keV {gamma} transitions decaying from the 2056-keV 4{sup +} state. The measured {ital E}2 transition probabilities support the assignment of the 4{sup +} state as a two-phonon {gamma}-vibrational state.
