New ion-guide for the production of beams of neutron-rich nuclei between Z=20-28

It has been shown for the first time that quasi- and deep-inelastic reactions can be successfully incorporated into the conventional Ion-Guide Isotope Separator On-Line (IGISOL) technique. This is of particular interest for characterizing the decay properties of refractory elements and is applied to neutron-rich nuclei between Z=20-28. As a first step of this project, the kinematics of quasi- and deep-inelastic reactions, such as 197Au(65Cu,X)Y, were studied. Based on these studies, a specialized IGISOL target chamber was designed and built. This chamber was tested in on- and off-line conditions at the Jyväskylä IGISOL facility. Yields of radioactive, projectile-like species such as 62, 63Co are about 0.8 ions/s/pnA corresponding to a total IGISOL efficiency of about 0.06%.
