Manifestation of clustering in the 252Cf(sf) and 249Cf(nth,f) reactions

Manifestations of Clustering in Binary and Ternary Fission of Low Excited Heavy Nuclei

“…This structure will further be termed as vertical ridges. An example of such fine structure in 252 Cf (sf) is shown in Figure 5 [5]. The position of the vertical ridges well agrees with the tops of the known isotopic distributions.…”

“…The map under discussion vividly demonstrates the role of the magic clusters in the body of the fissioning system in the form of fission modes. Actually, the ruptures occurred while the system descents along the distinct valley provide the fission fragments observed experimentally and treated as the appropriate fission mode [5]. Similar "visual" analysis of the nuclear shape in deformation process let authors of work [7] to reveal clustering in quasi-fission reactions leading to super-heavy systems.…”

“…Visual proof of clustering of the fissioning system along the descent from the fission barrier was obtained in Refs. [5,6]. Figure 1 shows potential energy of the fissioning nucleus 246 Cm corresponding to the bottoms of the potential valleys as the function of parameter Q proportional to the quadrupole moment of the system.…”

Half-Lives for Proton Emission, Alpha Decay, Cluster Radioactivity, and Cold Fission Processes Calculated in a Unified Theoretical Framework

“…Although many theoretical and experimental studies on cold fission processes [74][75][76] have been carried out in the last decade, there is not yet a systematic work that gives the predicted half lives for the possible cases of these processes for heavy parent nuclei.…”

Relationship between dinuclear systems and nuclei in highly deformed states

“…quasi-molecular states, was already mentioned in [16,17]. Besides theoretical work, there are experimental evidences for the existence of the cluster-type configurations in fissioning nuclei [18]. The validity of the cluster approach for heavier nuclei has been investigated in [19][20][21][22].…”
