Abstract
| The ISOLDE facility at CERN has been producing a broad range of radioactive beams for more than 30 years. The present low-energy beams (60 keV) of ISOLDE will soon be complemented by a post- accelerator, REX-ISOLDE, currently under construction. A novel scheme of trapping, cooling and charge-state breeding has been devised, which allows for a short, cost-effective linac reaching 0.8-2.2 MeV /u. The original physics aim of the REX-ISOLDE experiment is to probe the weakening of the magic numbers N=20,28 when going to extremely neutron-rich species by Coulomb excitation and neutron transfer reactions. For this purpose, a highly efficient Ge-detector array will be used, the MINIBALL. A number of other experiments are as well approved or planned. (14 refs). |
