Production of Super Heavy Elements at GANIL: Present Status and Perspectives

Ins. Fyziki Uniw., Krakow, Polandproceeding to the ASR2001 Conference, to be publishedin the Journal of Nuclear and Radiochemical Sciences (june 2002)AbstractExperiments on the production and study of superheavy nuclei have been un-dertaken at GANIL taking advantages of the powerful velocity filter LISE3 andthe high intensity ECR ion sources. A complete set-up has been built: - reactionchamber containing large rotating wheels, - slits and beam profiler at mid-filter,- detection chamber with time-of-flight and Silicon detectors for identifying evap-oration residues and their decay products. The response was checked via fusionreactions with known cross sections producing known α-decay chains and fissionfragments. Excellent transmission of evaporation residues and rejection factor forthe primary beam were obtained. This device is presented together with the resultsobtained in our last experiments and our future plans are discussed.
