摘要：
The EGO calorimeter of the Canadian 8 pi gamma-ray spectrometer was used to select the weak 2p channel in Ni-Ni fusion reactions, populating proton-rich Xe-114 and Xe-116. Lifetimes were measured for transitions within the low-lying positive and negative parity bands in Xe-114,Xe-116. Measured B(E2) values within the positive parity band were compared to calculations with algebraic models. Measured B(E2) values within the negative parity band in Xe-114 suggest a change in structure relative to that of the same band in the heavier xenon isotopes.
