An IN2P3-JINR collaboration has launched a project called GABRIELA at the Flerov
Laboratory for Nuclear Reactions (FLNR) at the Joint Institute for Nuclear Research (JINR) in
Dubna (Russia). The goal of the project is to perform gamma-ray and internal conversion electron
spectroscopy of heavy nuclei produced in fusion-evaporation reactions and transported to the focal
plane of the recoil separator VASSILISSA. During five experimental campaigns of GABRIELA,
the detection system has gained in sensitivity and new spectroscopic information has been obtained
for 249Fm, 251Fm, 253No and 255Lr |
