Abstract

The phenomenon of fusion hindrance may have important consequences on the nuclear processes occurring in astrophysical scenarios, if it is a general behaviour of heavy-ion fusion at extreme sub-barrier energies, including reactions involving lighter systems, e.g. reactions in the carbon and oxygen burning stages of heavy stars. The hindrance is generally identified by the observation of a maximum of the S-factor vs. energy. Whether there is an S-factor maximum at very low energies for systems with a positive fusion Q-value is an experimentally challenging question. Our aim has been to search evidence for fusion hindrance in 12C + 24Mg which is a medium-light systems with positive Q-value for fusion, besides the heavier cases where hindrance is recognised to be a general phenomenon. The experiment has been performed at the XTU Tandem accelerator of LNL by directly detecting the fusion evaporation residues at very forward angles. The excitation function has been extended down to ≃10μb, i.e. 4 orders of magnitude lower than previous measurements and we observe that the S-factor develops a clear maximum vs. energy. Coupled-Channels calculations using a Woods-Saxon potential give a good account of the data near and above the barrier but over predict the cross sections at very low energies. Therefore the hindrance phenomenon is clearly recognised in 12 C + 24 Mg with an energy threshold that nicely fits the systematics in several medium-light systems. The fusion cross sections at the hindrance threshold show that the highest value (as=1.6mb) is indeed found for this system. It may be possible to extend the measurements further down in energy.

Abstract

International audience; Cluster resonances in light heavy-ion systems like $^{12}$C+$^{12}$C and $^{12}$C+$^{16}$O may have a major impact on astrophysics stellar scenarios. Resonant radiative capture reactions have been studied for these systems at energies at and slightly below their Coulomb barriers to investigate the possible $^{12}$C-$^{12}$Cand $^{12}$C-$^{16}$O molecular origin of the resonances. Spins have been attributed to the resonances and specificities of their γ-decay have been identified. At deep sub-barrier energies, a fusion cross section measurement using the particle-γ coincidence technique is discussed for the $^{12}$C+$^{12}$C system. A new project is presented to possibly extend the $^{12}$C+$^{12}$C low-energy S factor study.

Abstract

A modified version of the time-differential recoil-in-vacuum (TDRIV) method, adapted for use with radioactive beams, was applied for the first time to perform a g-factor measurement on the first-excited state in 24Mg (Ex = 1.369 MeV, t = 1.97 ps). A high precision g-factor value was obtained using predominantly H-like ions. The results obtained demonstrate the versatility of the new approach and have the precision needed for stringent tests of shell model calculations.

Abstract

Electromagnetic transitions from deformed structures based on $\alpha$ configurations or on heavier clusters are discussed, drawing the link between multiparticle-multihole excited bands and cluster structures. Enhanced E2 and E1 transitions are reviewed in the light nuclei, $^8$Be, $^{10}$Be, $^{12}$C, $^{16}$O, $^{18}$O and heavier ones like $^{212}$Po. Connections between cluster structures and superdeformed configurations in $^{36}$Ar and $^{40}$Ca are discussed. What the cluster states based on heavier substructures like $^{12}$C and $^{16}$O are concerned, recent results on the resonant radiative capture reaction $^{12}$C($^{16}$O,$\gamma$)$^{28}$Si are presented, in particular the strong decay mode involving the feeding of low-lying $^{28}$Si 1$^+$ and 2$^+$ T=1 states by enhanced M1 isovector transitions., Comment: Plenary talk presented at the Cluster12, Conference, 10th International Conference on Clustering Aspects of Nuclear Structure and Dynamics, Debrecen, Hungary, 24-28 September 2012
