Abstract

The electronic structure of thorium (Th) in low- and high-temperature cubic phases under normal conditions and pressure has been studied using the LDA + U + SO method. Since a correct description of the physical properties of Th and other metals of the actinide series requires taking into account both the spin-orbit coupling and Coulomb interactions, the parameters of these interactions have been additionally calculated. It is established that applied pressure leads to broadening of the 5f electron states in metallic Th and causes a significant increase in their population.
