Lifetimes and transition probabilities for low-lying yrast levels in Te-130,Te-132
Lifetimes have been measured for the low-lying yrast levels of Te-130,Te-132 using gamma - gamma fast timing methods. The excited states were populated in beta(-) and IT decay of fission fragments, mass-separated by the Lohengrin separator at Institut Laue-Langevin. Four LaBr3(Ce) detectors, placed...

| Sumario: | Lifetimes have been measured for the low-lying yrast levels of Te-130,Te-132 using gamma - gamma fast timing methods. The excited states were populated in beta(-) and IT decay of fission fragments, mass-separated by the Lohengrin separator at Institut Laue-Langevin. Four LaBr3(Ce) detectors, placed at the focal plane of the spectrometer, were used for the gamma -gamma fast timing measurement. Lifetimes of mu s isomers were measured using coincidence of an ionization chamber with two Clover HPGe detectors. Themeasured lifetimes and absolute transition probabilities are discussed in the light of systematics with the neighboring nuclei. Large basis shell model calculations have been performed to interpret the level structure and transition probabilities in these even mass Te isotopes. |
