“…In spring 1974, the fission product mass separator [3] at the high flux reactor in Grenoble was put in operation. In addition, new physical methods to determine the nuclear charge of mass separated fission products have been developed [4,5]. Some results on nuclear charge distributions have been reported recently [6,7].…”

“…From physical methods, ionic charge states and masses can be respectively deduced from the energy-loss and total energy measurements. The nuclear-charge identification is then limited to the light fragments [3][4][5] due to the strong fluctuation of ionic charge states preventing a clear assignment of the atomic number in the heavy group. Moreover, fission fragments having a low recoil energy, their energy straggling in dead layers limits the resolution to σ ∼ 1.5 MeV [6].…”

Abstract. SOFIA (Studies On Fission with Aladin) is a new experimental set-up dedicated to accurate measurement of fission-fragments isotopic yields. It is located at GSI, the only place to use inverse kinematics at relativistic energies in order to study the (γ,f) electromagnetic-induced fission. The SOFIA set-up is a large-acceptance magnetic spectrometer, which allows to fully identify both fission fragments in coincidence on the whole fission-fragment range. This paper will report on fission yields obtained in 234,235,236,238 U(γ,f) reactions.

“…Therefore, there exist absolutely no data on full fission-fragment distributions for specific systems. Fission fragments of the light group could first be fully identified at the Lohengrin spectrograph at ILL, Grenoble with high-resolution energy-loss measurements [27,28]. However, these experiments remain limited to thermal-neutron-induced fission.…”

Abstract. With its powerful installations, GSI, Darmstadt, provides unique conditions for fundamental and applied research on a variety of subjects in nuclear physics and other fields with heavy-ion beams of stable and radioactive species. Intensive work on nuclear data is being made, e.g., on nuclear masses, half lives, nuclide yields from lowenergy fission, and nuclide production in spallation reactions. The interest in spallation reactions with primary proton energies around 1 GeV is motivated by the accelerator-driven system, dedicated to the incineration of nuclear waste. An innovative experimental method has been developed, based on inverse kinematics, which allowed for the first time to identify all reaction residues in-flight, using the high-resolution magnetic spectrometer FRS, and thus to determine full nuclide distributions. It also gives direct access to the reaction kinematics. During the last years, an experimental campaign has been carried out in a Europe-wide collaboration, investigating the spallation of several nuclei ranging from 56 Fe to 238 U. Complementary experiments were performed with a full-acceptance detection system, yielding total fission cross sections with high precision. Recently, another detection system using the largeacceptance ALADIN dipole and the LAND neutron detector was introduced to measure light particles in coincidence with the heavy residues. Another intense activity was dedicated to develop codes which cover the nuclear reactions occurring in an ADS in their full energy range and in all target materials involved. Most effort was invested in modelling the later de-excitation stage of the reaction, which is responsible for the salient features observed in the residual nuclide distributions due to the different possible de-excitation paths like evaporation of nucleons, light charged particles and intermediate-mass fragments, fission and multi-fragmentation. The future FAIR facility will provide primary beams with higher intensities and higher energies, a considerably extended variety of secondary beams, and a number of new installations, e.g., powerful magnetic spectrometers, storage rings and colliders. A new generation of experiments on fission-fragment yields with tagged photons using secondary beams is described as an example for future developments.
