摘要：
The actinide resources and production capabilities at Oak Ridge National Laboratory (ORNL) are reviewed, including potential electromagnetic separation of rare radioactive materials. The first experiments at the Dubna Gas Filled Recoil Separator (DGFRS) with a new digital detection system developed at ORNL and University of Tennessee Knoxville (UTK) are presented. These studies used (240)pu material provided by ORNL and mixed-Cf targets made at ORNL. The proposal to use an enriched Cf-251 target and a large dose of Fe-58 beam to reach the N = 184 shell closure and to observe new elements with Z = 124, 122 and 120 is discussed.
