“…This channel falls off quickly however, whilst the 2p2n decays in proportion to 1p with increasing distance. Previous studies of this reaction at energies closer to the barrier [16] found similar results, and interpreted this behaviour as evidence of clustering in 19 F, and in particular that the strong enhancement of 3p2n transfer was indicative of a direct (non-sequential) transfer of p + α. Here it is shown that this enhancement seems to disappear at larger internuclear separations.…”

“…An experiment was performed at the Heavy Ion Accelerator facility at the ANU in June 2013, in which a 208 Pb target was bombarded with 16 O, 18 O, and 19 F beams, at energies from 100% to 90% of the Coulomb barrier V B . The experimental setup is shown in Fig 1. The light projectilelike fragments were detected at 160.6 o , with yields normalized to elastic scattering events in two forward angle monitor detectors to obtain absolute transfer probabilities.…”

“…Cluster transfer is a possible long-range dissipation mechanism [6], since the cluster states that might be expected to participate are predicted to be radially diffuse [7]. In this work multi-nucleon transfer probabilities and excitation energy distributions in 16,18 O, 19 F + 208 Pb spanning the well-below to above barrier energy regions have been measured. The chosen projectiles have been previously identified to exhibit clustering properties in the context of structure studies [8].…”

Abstract. Multinucleon transfer probabilities and excitation energy distributions have been measured in 16,18 O, 19 F + 208 Pb at energies between 90% -100% of the Coulomb barrier. A strong 2p2n enhancement is observed for all reactions, though most spectacularly in the 18 O induced reaction. Results are interpreted in terms of the Semiclassical model, which seems to suggest α-cluster transfer in all studied systems. The relation to cluster-states in the projectile is discussed, with the experimental results consistent with previous structure studies. Dissipation of energy in the collisions of 18 O is compared between different reaction modes, with cluster transfer associated with dissipation over a large number of internal states. Cluster transfer is shown to be a long range dissipation mechanism, which will inform the development of future models to treat these dynamic processes in reactions.

“…This result was previously seen also in the reaction 19 F + 232 Th at near-barrrier energies as reported in Ref. [23]. Figures 14 and 15 show the excitation spectra of the reaction products in the 12 C and 14 C, in which it is evident that the reaction products can be produced at high excitation energies.…”

Abstract. Nucleon and cluster transfer probabilities have been measured in the collisions of 16,18 O, 19 F with 204,208 Pb, 209 Bi for charge stripping channels down to ΔZ = -3. Strong evidence of correlated nucleon transfer has been observed in particular channels, and neighbouring systems are seen to differ significantly in their behaviour. New measurements were made using an improved ΔE-E telescope. The back-scattered projectilelike fragments were measured in the telescope at θ lab = 160.6 • , and in combination with monitor detectors at forward angles allowed determination of absolute transfer probabilities. The improved design allows isotopic yields to be measured with greater precision.

“…At this energy, transfer reactions represent about 10% of the total cross section [6]. The actinides produced by transfer reactions are tagged by the detection and the identification of the target recoils in a highly segmented annular silicon telescope, SPIDER [7], as shown in figure 1 (a).…”

Two fission experiments have been performed at GANIL using 238 U beams at different energies and light targets. Different fissioning systems were produced with excitation energies from 10 to 230 MeV and their decay by fission was investigated with GANIL spectrometers. Preliminary fission-fragment isotopic distributions have been obtained. The evolution with impinging energy of their properties, the neutron excess and the width of the neutron-number distributions, gives important insights into the dynamics of fusion-fission mechanism.
