An improved system for fast, continuous chemical separations (“SISAK 2”) in nuclear spectroscopic studies

Abstract An improved rapid, continuous solvent extraction system (“SISAK 2”) is described. The system is connected to a gas-jet installed at the Mainz reactor. It allows single or multistage chemical separations of liquid phases by means of specially designed centrifuges within ∼1 s per stage. The application of this system to study short-lived nuclides is exemplified for neutron-rich lanthanum and cerium isotopes produced by fission.
