Potential energy effects and diffusion in the relaxed components of the reaction 197Au + 40Ar at 288 and 340 MeV bombarding energies

The reaction mechanism in the system132Xe+56Fe at 5.73 MeV/u: Evidence for a new type of strongly damped collisions

“…Although the separation becomes less clear at the highest energies, the distinction between the two components can always be made. Similar results were obtained for the system 4~ investigated at various energies by Borderie et al [25] and Moretto et al [26], although suggests explaining both components at the higher energies in terms of a diffusion model. In a radiochemical study of 132Xe+56Fe at the lower energy of effectively 4.8 MeV/u in a thick target Habbestad-W~itzig et al [27] found QE, DI, FF and ER reactions quite well separated in the mass yield distributions.…”

Evidence for the characterization of heavy-ion reactions by the ratioE/B

“…In Table 1 the lifetime of the intermediate complex for /rms has been estimated using (6). For the system 620 MeV S6Kr+ t9VAu one obtains good agreement between the estimate (8.3 x 10 -zz s) from (6) and the corresponding value (ll.7x 10 -z2 s) obtained from diffusion model calculations [9].…”

“…If the values of zlife and /22 estimated from (6) and (9) represent approximate averages, then the calculated variances (/22 Zlife) given in Table 1 may roughly correspond to the variances of the experimental total charge distributions. For 170MeV 4~ for example, we estimate a variance of 9.0 which is much larger than the experimental value of 1.7 obtained by a Gaussian fit to the charge distribution in Figure la (omitting points in the interval 16<Z<20 and after subtracting out the symmetric component).…”

“…2014 [4] beyond which no compound nucleus formation takes place. In heavy and medium-weight composite systems some study has been made of strongly inelastic processes [5,6] including fission [7] and quasifission [8,9] which together with complete fusion and …”

“…Measurements of the cross-section for formation of a compound system as a function of energy have been used to explore the fusion barrier [2] and the results have been interpreted in terms of a critical angular momentum [3] or a critical radius [4] beyond which no compound nucleus formation takes place. In heavy and medium-weight composite systems some study has been made of strongly inelastic processes [5,6] including fission [7] and quasifission [8,9] which together with complete fusion and direct reactions make up the total reaction cross-section. The strongly inelastic processes become more important with increasing bombarding energy.…”
