Abstract
The shock Hugoniot equation of state for thorium has been computed, using the pseudopotential methods. The nuclear Gruneisen parameters ( gamma ), used in evaluating the ionic vibration contributions have been derived from phonon frequencies. The electronic thermal contribution is obtained using Thomas-Fermi-Dirac (TFD) theory, as the electronic Gruneisen parameter varied with temperature in accordance with TFD theory. The computed P-V curves is in agreement with the data of McQueen and Marsh (1960) although the Hugoniot temperatures at high compressions are different from those derived by them.
