Absolute fission probabilities of highly excited nuclei (U-238, Th-232
, Bi-209, Au-197, Ho-165, Sn-119, Ag-nat, Mo-100, Y-89, and Cu-nat tar
gets) produced by 1.9 GeV/c antiprotons were measured. The experiments
were performed at LEAR/CERN with a 4 pi neutron and 4 pi charged-part
icle detector. The results are compared with experimental data from st
opped-antiproton annihilation and calculations based on the intranucle
ar cascade and evaporation models. Annihilation cross sections were al
so determined for the targets listed above.
