Light-particle emission from Au+Au collisions has been studied in the bombarding-energy range 100-250 A·MeV, using DeltaE- ER telescopes in coincidence with the FOPI detector in its phase I configuration. Center-of-mass energy spectra have been measured for Z = 1,2 isotopes emitted in central collisions at CM polar angles between 60° and 90°. Evidence for a collective expansion is reported, on the basis of the mean kinetic energies of hydrogen isotopes. Comparison is presented with statistical calculations (WIX code). For CM kinetic energy spectra, fair agreement is found between data and a recently developed transport model.

Prompt fission induced by anti-proton annihilation at rest on heavy nuclei

Bocquet, J.P. ; Malek, Fairouz ; Nifenecker, H. ; et al.

Inspire Record 343226 DOI 10.17182/hepdata.16577

Antiproton induced fission probabilities of U238, Bi209, Pb208 and Au177 are reported together with the mass distribution of the fission fragments in the U238 and Bi209 cases. The charged particles multiplicities observed in co-incidence with fission have, also, been measured for U and Bi and are presented.
