94. Coupled-channels analyses for $^{9,11}$Li + $^{208}$Pb fusion reactions with multi-neutron transfer couplings

Oral contribution

We discuss the role of two-neutron transfer processes in the fusion reaction of the $^{9,11}$Li + $^{208}$Pb systems.
We first analyze the $^{9}$Li + $^{208}$Pb reaction by taking into account the coupling to the
$^{7}$Li + $^{210}$Pb channel. To this end, we assume that two neutrons are directly transferred to a single effective channel in $^{210}$Pb and solve the coupled-channels...

34. Elastic scattering measurement for the 10Be+natPb reaction at above the Coulomb barrier energy

Oral contribution

Recently, elastic scattering has been of great interest to study the information on the exotic structure and reaction mechanism of the weakly bound nuclei. In the last few years, some of the experimental and theoretical works have appeared for proton as well as neutron-rich nuclei at above and near barrier energies [1-3]. Interesting features have been discovered in the study of the elastic...

13. Interplay of charge-clustering and weak binding in direct reactions of 8Li

Dr Kaitlin J. Cook (Australian National University)

Oral contribution

A critical problem affecting studies and uses of light weakly-bound nuclei is the suppression of above-barrier complete fusion (e.g. [1]). The cause of suppression is uncertain, particularly for exotic neutron-rich radioactive nuclei. The suppression is thought to be related to their low thresholds for breakup into charged clusters. The observation of fusion suppression in the neutron-rich...

129. Direct reaction mechanisms and fusion hindrance of light, weakly-bound nuclides

Dr Edward Simpson (Australian National University)

06/06/2018, 11:39

Oral contribution

Near-barrier collisions involving light, weakly-bound nuclei exhibit a diverse range of reaction phenomenon, including direct breakup, nucleon transfer, and fusion. The interplay of these different mechanisms is of great interest, since fusion reactions of 6,7,8Li, 9Be and 10,11B have been found to be significantly suppressed, by up to 35% [see 1 and refs. therein]. The root cause of this...
