Fast separation of isobars on ISOL facility collector

Creators

Description

Volatility of Rb, Sr, Y, Ba, some rare earth elements, Ra, Ac and Th, implantated in a tantalum collector with 45 keV energy is investigated. The collector heating during 180 s in vacuum results in the separation of implantated elements. Separation coefficients are as follows: sup(α)Sr/Rb=14/1390 K/, sup(α)Y/Sr=28/1680 K/, sup(α)La/Ba=8/1590 K/, sup(α)Sm/Eu=3/1470 K/, sup(α)Gd/Eu=22/1620 K/, sup(α)Tm/Yb=8/1600 K/, sup(α)Lu/Yb=38/1700 K/ and sup(α)Ac/Ra=sup(α)Th/Ra=030/1650 K/. The contributions of diffusion and desorption to the volatility process of implantated elements and prospects for application of the proposed method for separation of isobars on ISOL Facility collector are discussed
