摘要：

A chemical separation method based on reversed-phase chromatography has been developed to separate the group five elements from the reaction products produced in the bombardment of Am-243 with Ca-48 ions. Decontamination factors on the order of 10(6) were achieved for group-three elements such as americium, and 10(7) or more for selected reaction products as measured by gamma-ray spectrometry pre- and post-chemistry. Details of the chemical separation scheme are discussed and compared to previously reported results.
