WebCommissioned in 2000, ISAC produces beams of rare isotopes for experiments primarily studying nuclear structure and nuclear astrophysics. Irradiation of uranium or thorium targets with protons at 480 MeV results in the production of a number of isotopes that are extracted into a heterogeneous ion beam. WebThe accurate determination of thorium (Th 4+) in the presence of uranyl ions (UO 2 2+) is a challenge facing analytical chemists.In this article, a solidified floating organic drop …
