Latest results obtained at GANIL with new target-source systems dedicated to radioactive ion production

Two new target-source systems have been realized and used to produce radioactive elements with primary beams of Kr-78 (68.5 A MeV) and Ar-36 (95 A MeV). The production yields of Kr-73,Kr-72, Ar-35,Ar-33,Ar-32, P-30,P-29, S-31,S-30, Cl-34,Cl-33,Cl-32 and of some other condensable elements such as Br-73,Br-72 and Se-73,Se-71 are presented. The results of the improvements between the two versions of the production system are discussed. (C) 2004 American Institute of Physics.
