Quasifission occurs in fully damped heavy-ion collisions following a significant mass transfer between the fragments, without formation of a compound nucleus. It is the primary reaction mechanism hindering the formation of a superheavy compound nucleus after the collision partners have reached contact. As in fission, quasi-fission is expected to be affected by quantum effects leading to...
Fast-timing measurements have been performed to investigate the nuclear structure of the A =
83 isobars 83Se and 83Br, with the aim of studying the evolution of collectivity and possible shape
coexistence in the vicinity of the N = 50 shell closure.
The experiment was carried out at the LOHENGRIN recoil mass separator at the Institut
Laue-Langevin. Neutron-induced fission products were...
We present results of experiment focused on a previously unknown fission characteristic of Hg-194 perfromed at the ALTO facility during the campaign with the nu-ball-2 spectrometer. The nuclide of interest was created in a fusion reaction of C-12 beam on a thick W-182 target. Independent fission yields of even-even nuclei were determined by detecting gamma-gamma cascades in the fission...
Despite decades of study, accurate modeling of nuclear fission remains difficult, as a wide variety of theoretical approaches—microscopic, macroscopic, and phenomenological models—are based on different underlying assumptions. To date, despite this diversity of approaches, none of the currently existing models can predict the angular-momentum generation mechanism with satisfactory accuracy. To...
