Abstract

The blocking technique in single crystals has been applied to reaction time measurements for the $^{238}$U + Ge system at 6.1 MeV/nucleon. Backed up with a reaction mechanism analysis using the INDRA 4$\pi$ detector, it provides a direct experimental evidence for Z = 124 compound nuclei living longer than 10−18s, indicating thus very high fission barriers for this element.
