Abstract
Thin self-supporting 123Sb targets were needed for studies using GAMMASPHERE investigating transverse wobbling in the highly-deformed triaxial nucleus 135Pr. The experiment was carried out using the 123Sb(16O,4n)135Pr reaction with the 80 MeV 16O beam provided by the ATLAS accelerator facility. In particle–particle coincidence measurements 121Sb targets were irradiated with a 332 MeV 28Si beam from ATLAS to measure evaporation residues and fission. The antimony targets were prepared self-supporting by the method of physical vapor deposition onto polished glass substrates or on various backing materials. Target thicknesses on the order of 500–1,000 μg/cm2 were obtained and used for the experiments. Details of the target production and performance in beam will be discussed.
