| الوصف: | Total cross sections for proton- and deuteron-induced-fission of ${}^{208}$Pb and ${}^{238}$U have been determined in the energy range between 500 MeV and 1 GeV. The experiment has been performed in inverse kinematics at GSI Darmstadt, facilitating the counting of the projectiles and the identification of the reaction products. High precision between 5$%$ and 7$%$ has been achieved by individually counting the beam particles and by registering both fission fragments in coincidence with high efficiency and full $Z$ resolution. Fission was clearly distinguished from other reaction channels. The results were found to deviate by up to 30$%$ from Prokofiev's systematics on total fission cross sections. There is good agreement with an elaborate experiment performed in direct kinematics. |
