“…If we compare their results to the FRS ones at 1 GeV [4], for the fission isotopes measured in both experiments and after cumulation of the FRS cross-sections, we find that ref. [44] cross-sections are 31% higher on the average.…”

“…In order to see if this behaviour could be due to a more general trend related to the difference of experimental techniques, we have carried out a comparison of 1000 A MeV data from Gloris et al in the same paper with the data obtained previously by our collaboration at GSI [4]. The results of the ratio of crosssections (FRS/γ-spectrometry) are shown in Fig.…”

“…A detailed description of the experimental set-up and the analysis method can be found in previous publications [1,4,7]. Therefore we just recall here the detection principle and point out the specificities and difficulties related to the experiment at 500 A MeV.…”

“…Since several years a large effort has been devoted at GSI to the measurements of evaporation residues and fission fragments in spallation reactions induced by proton and deuteron on gold [1,2], lead [3,4,5] and uranium [6,7]. The primary trigger for these new measurements was the need for precise spallation data which were required by various ambitious projects like neutron spallation sources [8,9] and accelerator-driven systems (ADS) for incineration of nuclear waste [10,11,12].…”

“…Experiments enabling a detailed understanding of the mechanism and involving various target elements and bombarding energies are thus required for this purpose. As shown in [1,3,4,7], the measurement of the complete isotopic and velocity distributions really allows to test the models and no such data were existing around 500 MeV.…”

Nuclide cross-sections of fission fragments in the reaction 208Pb + p at 500 A MeV

The isotopic distributions and recoil velocities of the fission fragments produced in the spallation reaction 208 P b + p at 500 A MeV have been measured using the inverse-kinematics technique, a lead beam onto a liquid-hydrogen target, and the high-resolution spectrometer FRS at GSI. The shapes of the different distributions are found in good agreement with previously published data while the deduced total fission cross-section is higher than expected from existing systematics and some previous measurements. From the experimental data, the characteristics of the average fissioning system can be reconstructed in charge, mass and excitation energy, and the average number of post-fission neutrons can be inferred. The results are also compared to different models describing the spallation reaction. The intranuclear cascade code INCL4 followed by the de-excitation code ABLA is shown to describe reasonably well the evolution of the isotopic distribution shapes between 500 and 1000 A MeV.
