Abstract : Total fission cross sections of 208Pb induced by protons have been determined at 370A, 500A, and 650A MeV.
The experiment was performed at GSI Darmstadt where the combined use of the inverse kinematics technique
with an efficient detection setup allowed us to determine these cross sections with an uncertainty below 6%. This
result was achieved by an accurate beam selection and registration of both fission fragments in coincidence which
were also clearly distinguished from other reaction channels. These data solve existing discrepancies between
previous measurements, providing new values for the Prokofiev systematics. The data also allow us to investigate
the fission process at high excitation energies and small deformations. In particular, some fundamental questions
about fission dynamics have been addressed, which are related to dissipative and transient time effects.
