✦ Synopsis

Within the collaboration Dubna-GANIL (Caen, France) -IPN (Orsay, France) -NPI (Rez, Czech Republic) -IAP (Bucharest, Romania) at GANIL and the Dubna U400M accelerator, experiments have been carried out to study elastic scattering, fusion and fission using secondary ion beams of 6He, "Li and 'B. The fission crosssection for the 6He isotopes has been found to be significantly higher than for the 4He nuclei. This enhancement depends mainly on the entrance channel and it is connected with the neutron skin of the 6He nuclei.

Also, investigation of the elastic scattering of "Li (neutron halo), 'Be and 8B (proton halo) has been performed. The microscopic analysis supports the existence of a neutron halo in "Li and the proton skin in 8B and 'Be. Perspectives for investigations in this field at the Laboratory of Nuclear Reactions JINR are also discussed.
