Abstract : Picosecond lifetimes of excited states in neutron-rich Xe isotopes were measured at the Institut Laue-
Langevin via $\gamma$-ray spectroscopy of fission fragments from neutron-induced fission of 235U and 241Pu
targets. The data collected with the recently installed fast timing array FATIMA in combination with
the EXOGAM Ge array were analysed using the new generalized centroid difference method. Our
aim is to study the quadrupole and octupole collectivity, arising in the mass region beyond the doubly
magic 132Sn, by means of transition probabilities. These can be calculated from the directly measured
lifetimes.
