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

抄録

Experiments on the production and study of superheavy nuclei have been undertaken at GANIL taking advantages of the powerful velocity filter LISE3 and the high intensity ECR ion sources. A complete setup has been built: -reaction chamber containing large rotating wheels, - slits and beam profiler at mid-filter, - detection chamber with time-of-flight and Silicon detectors for identifying evaporation residues and their decay products. The response was checked via fusion reactions with known cross sections producing known α-decay chains and fission fragments. Excellent transmission of evaporation residues and rejection factor for the primary beam were obtained. This device is presented together with the results obtained in our last experiments and our future plans are discussed.
