Development of an extraction system for the separation of dubnium from rutherfordium using MIBK and HCl/HF solutions

Abstract

A chemical separation system was developed to separate group 4 and 5 elements using extraction from HCl/HF solution into methyl-isobutyl-ketone (MIBK). The system is proposed to be applied for a confident assignment of the spontaneous fissioning radionuclide produced as decay product of element 115 either as dubnium (Db,

Brief encounters with dubnium

“…Crucial for these experiments is comparison with lighter analogues under the same circumstances. For example, radioactive isotopes of Hf and Ta, produced by neutron activation, were recently used to develop an extraction system for the separation of dubnium from its group 4 neighbour rutherfordium 4 .…”
