Peripheral collisions of 40 MeV/u $^{14}$N with a $^{197}$Au target

Pruneau, C. ; Potvin, L. ; Roy, R. ; et al.

Nucl.Phys.A 500 (1989) 168-194, 1989.

A 32-phoswich detector array has been used in conjunction with two Si-telescopes to detect, in coincidence, light and projectile-like fragments produced in the reaction 14N + 197Au at 560 MeV. Inclusive and semi-exclusive cross sections are given. Angular correlations and invariant cross-section velocity distributions of light particles in coincidence with projectile-like fragments are used to deduce the dominant reaction mechanisms. The transfer of nucleons to the target and sequential breakup of the quasi-projectile with or without pickup of target nucleons are clearly seen. Some evidence is found for a prompt breakup of the projectile into 10B + α followed by a dissipative interaction of the heavy fragment with the target.

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

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

Z.Phys.A 342 (1992) 183-189, 1992.

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.
