Cl35-induced fission and fissionlike reactions onNi58,62,Sn112,116,120,124, andPr141

Counter telescopes (gas $\Delta E$, Si-E) were used to measure angular distributions of binary yield products resulting from bombardment of ${}_{}{}^{58,62}{}_{}{}^{}\mathrm{Ni}$, ${}_{}{}^{112,116,120,124}{}_{}{}^{}\mathrm{Sn}$, and ${}_{}{}^{141}{}_{}{}^{}\mathrm{Pr}$ targets with ${}_{}{}^{35}{}_{}{}^{}\mathrm{Cl}$ beams at energies between 155 and 170 MeV. Results are presented for angular distributions averaged over bins two atomic numbers wide and integrated over all fragment atomic numbers. The Sn and Pr targets give yields consistent with an equilibrium fission mechanism according to charge distributions, kinetic energies, and angular distributions. The interpretation of yields from Ni targets is found to be more ambiguous. All systems give fragment energies consistent with semiempirical trend formulas, independent of asymmetry. Qualitative evidence for deep inelastic yields, in addition to fission yields, are found for Sn and Pr targets.
