%X Abstract This work describes the first real developments in radiochemistry around exotic radionuclides at the cyclotron of Orl¨¦ans focusing on the radiochemistry of two radiometals 165Er and 52Mn. For these developments, targets were irradiated during 0.5¨C2 h at a maximum current of 2 ¦̀A. All activities have been determined by radiotracer method. The production of 165Er from a natural Ho target that was irradiated is described. Higher activities of 165Er were obtained via deuteron irradiation then proton with lower ratio 165Er/ 166Ho (400/1 to 8/1). By using LN2 resin, the separation of adjacent lanthanides was made on various concentrations of HNO 3 (0.3 to 5 M). Weight coefficients (Dw) were defined in a batch test. Then, the first tests of separation on a semi-automated system were made: the ratio 166+natHo/ 165Er in an isolated fraction was significantly reduced (1294 ¡À 1183 ( n = 3)) but the reliability and reproducibility of the system must be improved. Then, a new Cr powder-based target for 52Mn production was designed. Its physical aspects such as mechanics, thermal resistance and porosity have been studied. Dw for various compositions of eluent Ethanol/HCl were evaluated by reducing contact time (1 h) comparative to the literature. A first evaluation of semi-automated separation Cr/Mn has been made.
