Title: Comprehensive analysis of fission-reaction properties in the nuclear spallation of {sup 238}U(1 GeV/nucleon) on deuterium

Abstract

Fission fragments of 1 GeV/nucleon {sup 238}U nuclei interacting with a deuterium target have been investigated with the Fragment Separator at GSI (Darmstadt) by measuring the isotopic production cross sections and fragment velocities. The combination of these two observables enabled to disentangle the high- and low-energy fission modes. Specific properties of these two modes were analyzed; in particular, the charge distribution of the fissioning projectile-like prefragments could be determined for the first time.
