采用三重γ符合方法，在布加勒斯特高纯锗（HPGe）和LaBr 3：Ce混合探测器阵列上，用束内快速定时方法测量了100个基态带。从测得的寿命中提取了约化的E2跃迁概率，并与相邻同位素中相应的可观测值进行了比较，显示出随着质量增加的平滑行为。将实验结果与sd和spdf玻色子空间中的相互作用玻色子模型以及受限β-软转子模型进行了比较，发现实验结果与实验结果符合得很好.
ground-state band were measured by using the in-beam fast-timing method with the Bucharest mixed high-purity germanium (HPGe) and LaBr3:Ce detector array using the triple-γ coincidence method. Reduced E2 transition probabilities were extracted from the measured lifetimes and compared with the corresponding observables in neighboring isotopes, showing a smooth behavior with increasing mass. The positive- and negative-parity states aswellas E1andE2transitionprobabilityratiosrevealedbytheseexperimentsarecomparedwiththeinteracting boson model in the sd and spdf boson space, and with the confined beta-soft rotor model, and are found to be in good agreement.
