Threshold energy for sub-barrier fusion hindrance phenomenon

The relationship between the threshold energy for a deep sub-barrier fusion hindrance phenomenon and the energy at which the regime of interaction changes (the turning-off of the nuclear forces and friction) in the sub-barrier capture process, is studied within the quantum diffusion approach. The quasielastic barrier distribution is shown to be a useful tool to clarify whether the slope of capture cross section changes at sub-barrier energies.Comment: 4 pages, 4 figures (accepted in Eur.

Sub-barrier capture reactions with 16,18^{16,18}O and 40,48^{40,48}Ca beams

Various sub-barrier capture reactions with beams $^{16,18}$O and $^{40,48}$Ca are treated within the quantum diffusion approach. The role of neutron transfer in these capture reactions is discussed. The quasielastic and capture barrier distributions are analyzed and compared with the recent experimental data.Comment: 8 pages, 9 figures, will be published in EPJA. arXiv admin note: substantial text overlap with arXiv:1211.433

Derivation of breakup probabilities from experimental elastic backscattering data

We suggest simple and useful method to extract breakup probabilities from the experimental elastic backscattering probabilities in the reactions with toughly and weakly bound nuclei.Comment: 4 page

Da li su hiperdeformirane jezgre nuklearne molekule?

A study of the interpretation of hyperdeformed nuclei as dinuclear quasimolecular cluster configurations is presented. Under the assumption that hyperdeformed states are quasimolecular resonance states, it is suggested to excite them directly in heavy-ion collisions. Signatures of hyperdeformed states in such reactions could be γ-transitions between these states and their decay into the nuclei forming the hyperdeformed nucleus.Razmatramo da li se hiperdeformirane jezgre mogu tumačiti kao dvonuklearni kvazimolekulski nakupinski sustavi. Pretpostavljajući da su hiperdeformirana stanja rezonantna stanja, predlaže se njihova uzbuda izravnim sudarima teških iona. Znaci hiperdeformiranih stanja u takvim reakcijama mogli bi biti γ-prijelazi među tim stanjima i njihov raspad u jezgre koje su proizvele hiperdeformiranu jezgru
