[en] The formation and decay of excited nuclei with masses around A = 200 are studied for excitation energy, ε ranging from 0 to 6 MeV/u. In case of multifragment emission, the authors find that: 1) The life-time of the excited nucleus before breaking is equal to 100-150 fm/c for ε values around 5 Mev/u. 2)The emission time (i.e. the interval between the emission of two fragments) evolves from a large value (τ>500 fm/c, sequential decay) when ε equals 2-3 MeV/u to a very small value (τ<50 fm/c, simultaneous decay) for ε values around 5 MeV/u. 3) Toroidal shapes are reached for the decay of the long-lived primary configurations

[en] The formation and decay of excited nuclei with masses around A=200 are studied for excitation energy, ε^* ranging from 0 to 6 MeV/u. For ε^* values up to 6 MeV/n, the various decay channels ending with one (evaporation), two (fission) or more (3, 4, 5) fragments still compete. In case of multifragment emission, we find that: - the life-time of the excited nucleus before breaking is equal to 100-150 fm/c for ε^* values around 5 MeV/u, - the emission time (i.e. the interval between the emission of two fragments) evolves from a large value (τ>1000 fm/c, sequential decay) when ε^* equals 2-3 MeV/u to a very small value (τ<50 fm/c, simultaneous decay) for ε^* values around 5 MeV/u.
