Extreme ground-state deformation of the N=Z nucleus 76Sr

Saturday 29 October 2011, by Antoine Lemasson // 4. Seminar, Schools, and Workshops

Abstract The shape of the atomic nucleus is determined by the interplay of macroscopic and microscopic effects within this quantum mechanical many-body system. Self-conjugate nuclei give an opportunity to study the role of np correlations in deformation and have attracted a great interest due to drastic shape evolution along the N=Z line. Strong ground-state deformation is expected to occur for N=Z nuclei above Z=36 from the 2+ state energy systematic as well as from theoretical (...) Read next

Fusion of the most neutron-rich nucleus 8He : Recent results from GANIL

5th International Conference FUSION11, Saint Malo : France (2011)

Thursday 12 May 2011, by Antoine Lemasson // 3. Conferences Proceedings

A. Lemasson, 5th International Conference FUSION11, Saint Malo : France. EPJ Web of Conferences, 17, 01003 (2011) DOI | HAL | BIB Abstract Re-accelerated radioactive ions beams of 8He from the SPIRAL facility at GANIL have been used to perform the first experimental investigations at energies around the Coulomb barrier of fusion and direct reactions with the most neutron rich 8He. Two experiments (in the 8He+65Cu and 8He+197Au systems) have been performed, using the complementarity of (...) Read next

Pair and single neutron transfer with Borromean 8He

Wednesday 2 March 2011, by Antoine Lemasson // 2. Peer reviewed

Direct observation of the survival of 199Au residues after 2n transfer in the 8He+197Au system and the absence of the corresponding 67Cu in the 8He+65Cu system at various energies are reported. The measurements of the surprisingly large cross sections for 199Au, coupled with the integral cross sections for the various Au residues, is used to obtain the first model-independent lower limits on (...)

Reactions with the double-Borromean nucleus 8He

Sunday 17 October 2010, by Antoine Lemasson // 2. Peer reviewed

Differential cross-sections for elastic scattering and neutron transfer reactions along with cross-sections for fusion in the 8He+65Cu system are reported at energies above the Coulomb barrier (Elab = 19.9 and 30.6 MeV). The present work demonstrates the feasibility of using inclusive measurements of characteristic in-beam g rays with low-intensity ( 105 pps) radioactive ion beams to obtain (...) Read next

Fusion and direct reactions around the Coulomb barrier with the neutron-rich 8He

Extended Thesis Summary

Monday 20 September 2010, by Antoine Lemasson // 1. PhD Thesis

When two nuclei collide a multitude of processes can occur: in the field of the combined nuclear, Coulomb and centrifugal potential, the two nuclei can scatter (elastic scattering), either or both the nuclei can be excited to their intrinsic states (inelastic scattering), few nucleons can be exchanged between the colliding nuclei (transfer reactions), or the two nuclei can fuse to form a (...)

Abstract

Monday 20 September 2010, by Antoine Lemasson // 1. PhD Thesis

Fusion and direct reactions around the Coulomb barrier with the neutron-rich 8He Abstract Radioactive ion beams like 8He, open new possibilities to investigate the influence of new and exotic structures on reaction mechanisms. This thesis presents the first investigations of reactions of the weakly bound, Borromean nucleus, 8He, at energies around the Coulomb barrier. The low intensity (...) Read next
