摘要

Model experiments with W and Mo were performed to simulate on-line ion-exchange isolation of element 106 (seaborgium, Sg) from H₂SO₄ and H₂SO₄/HF solutions. Short-lived isotopes of W and Mo were prepared by Sm(24xMg,xn)W nuclear reaction performed on a U-400 cyclotron. Molybdenum isotopes were prepared on an MT-25 microtron (Flerov Laboratory of Nuclear Reactions, JINR, Dubna) by fission of 235U with photoneutrons. The feasibility of isolation and chemical study of 265Sg in the course of its preparation and of identification of this radionuclide by long-lived daughter product, 253Fm, was demonstrated. The correlation of ion-exchange properties of W, Hf, Sr, and REE (TPE) under static and on-line conditions was revealed.
