نویسندگان
چکیده
Dedicated ionization chamber was built and installed to measure the energy loss of very heavy nuclei at 2.7 MeV/u produced in fusion reactions in inverse kinematics (beam of Pb). After going through the ionization chamber, products of reactions on C, O targets are implanted in a Si detector. Their identification through their alpha decay chain is ambiguous when their half-life is short. After calibration with Pb and Th nuclei, the ionization chamber signal allowed us to resolve these ambiguities. In the search for rare super-heavy nuclei produced in fusion reactions in inverse or symmetric kinematics, such a chamber will provide direct information on the nuclear charge of each implanted nucleus.

Recent progress from Jefferson Lab has significantly improved our understanding of the nucleon spin structure in the high-x region. Results of a precision measurement of the neutron spin asymmetry, A1, in the high-x (valence quark) region are discussed. The up and down quark spin distributions in the nucleon were extracted. A2 was also measured. The results were used, in combination with existi...

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 set-up 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 evaporatio...
