ABSTRACT

The LISE facility at the French national heavy ion accelerator GANIL was designed for the production of secondary beams of good optical quality. The preceding results are proof of the interest of medium energy heavy ions beams for the search of new exotic isotopes. All the results reported here are also proof of the outstanding performances of the LISE facility in the field of intermediate energy heavy ions physics. For the fragments rather close to the projectile mass the LISE spectrometer can deliver radioactive beams with a good energy resolution and a small amount of contamination. The optimum setting of the LISE spectrometer for a given reaction fragment relies on the reaction mechanism which defines its most probable energy and on the energy loss effects in the target. An additional stripper foil, an energy degrader or a thin positionsensitive detector can be placed behind the slits.
