Multinucleon transfer reactions in the 232Th+22Ne system

Mass transport mechanism in the collision of sulphur on medium-weight nuclei

“…The analysis of these data for different nuclei at different energies seems to indicate that the deep inelastic process as it was defined in the early times [1] is not the only observed mechanism. New processes like the fusion-fission [2] and more recently the fast fission process [3] were proposed in order to explain the experimental results.…”

Damped Heavy-Ion Collisions

“…It should also be kept in mind that nucleon evaporation may lead to a distortion of the spectra, resulting in a shift and a broadening (270). The effect of an increased bombarding energy on the fragment energy spectra is a general broadening and a shift of the most probable and the centroid energies to h igher values (4,23,24,200,274). For example, the spectrum of Mg-like fr ag ments from the reaction 232Th + 4 0 Ar (4) has a width of [40][41][42][43][44][45][46][47][48][49][50] MeV for a bom barding energy of ELab = 288 MeV, which increases to 80-90 MeV at ELab = 379 MeV.…”

“…In proceeding with the discussion of in-beam measurements " of the fragment isotopic distributions, one must refer to the extensive work of the Dubna group (4,32,230,232,235,(266)(267)(268), which studied IIB_, 15N_, 160_, 22Ne_, and 4°Ar_ induced reactions on 232Th, as well as the systems 12C+ 22Ne, '97Au +'60, and 94Zr + 22Ne. Production cross sections are measured fo r various isotopes at a fixed reaction angle.…”

Theoretical Methods in Medium-Energy and Heavy-Ion Physics

“…Until a more suitable force is discovered, it is essential to 243 phenomenologically modify the effective interaction in finite nuclei to yield the proper binding energy and density. Although painful for the purist to accept, and a step which, in principle, can be eliminated sometime in the future when we are less ignorant, this adjustment is crucial in making the mean field represent quantitatively what actually occurs in observed nuclei rather than in a fictitious universe held together with the Reid potential.…”
