Abstract:

The results of a laboratory investigations which involve 1 the vaporization of Thorium metal using rf heating, laser radiation heating by chemical reactions, and 2 the oxidation of thorium and Uranium, are presented. It has been , determined that the heat of vaporization for monoatomic thorium vapor is 143 Kcalmole. The ionization potentials of Thorium gas and Thorium oxide gas are quite low 5.5 -6.0eV, while that of thorium dioxide ThO2 is higher by 3eV. The rate constant for the production of thorium dioxide ion ThO2 was determined. The results of the laser blow-off study indicate that the spectrum from uranium metal produces both netural and singly ionized uranium atoms.
