Abstract.

Radioactive beams obtained via fragmentation of the projectile on a primary target have shown to be a powerful tool to produce exotic nuclei and some typical results obtained at GANIL in this area will be shown. To go further, and in particular , to get beams of exotic nuclei, new facilities have been developed recently. The physics expected from the use of these radioactive ion beam facilities is extremely ambitious as stated in the scientific motivations justifying their construction. At GANIL the SPIRAL facility is ready and will hopefully deliver the first radioactive beams in 2001. New experimental devices have been developed to fully exploit the potentiality expected from SPIRAL. EXOGAM is a new, efficient and powerful gamma ray spectrometer currently under installation at GANIL. The design and the performances expected from this array will be discussed.

Keywords:  Gamma-ray; spectroscopy; magic numbers; exotic nuclei, EXOGAM.
