Étude de la diffusion élastique et de la réaction d’échange de charge (p,n) avec des faisceaux exotiques légers riches en neutrons

Abstract : We have measured at GANIL, with the high resolution spectrometer SPEG, the elastic scattering of several neutron rich secondary beams (6He, 10Be and 11Be) on a polypropylene target and the charge exchange reaction p(6He, 6Li)n. These exotic beams were produced by nuclear fragmentation and re-focalized with the SISSI device (superconducting solenoids). The signature of a halo structure in these nuclei has been analysed. Special attention has been paid to several aspects of the associated calculations namely, the proton and neutron density distributions and the small binding energy for the last nucleons in these exotic nuclei. Break-up mechanisms are seen to play an important role in these nuclei
