An isotope separator for on-line operation at the 225-cm cyclotron in Stockholm has been constructed for studies of nuclides far from the line of β stability and produced by heavy-ion reactions. Its ability to prepare mass separated samples suitable for nuclear spectroscopy has been demonstrated for both neutron-rich and neutron-deficient nuclides. The equipment was tested in June 1969 by the separation of known mercury isotopes produced by (α, xn) reactions on platinum. The major part of the work has involved studies of separated products from α-particle induced fission of uranium. The beam of heavy ions extracted from the cyclotron is focused on a solid target inside the separator ion source. The nuclear reaction products are continuously released and ionized in the discharge chamber at high temperatures. Beams of electromagnetically separated nuclides are collected in front of various radiation detectors. A detector arrangement suitable for coincidence measurements on very short-lived isotopes is described as well as a tape transport system for the collected radioactive samples. The temperature of the target-ion source (1500°C) has permitted the separation of a large number of elements produced in fission. The most short-lived nuclides so far observed are 120Agm(T12=0.3 s) and96Rb(T12=0.2 s).
