Abstract
The fusion-fission channel of a heavy-ion reaction has been used in order t o produce at high-spin neutron-rich nuclei, from Ni up to La isotopes, whic h have been studied thanks to the very efficient gamma -array EUROGAM2. The different structures observed in the Ru-102,Ru-104,Ru-106,Ru-108 isotopes are compared with results of adequate self-consistent microscopical calcula tions in which the sole input is the effective Gogny force with the standar d parametrization D1S.
