Thomas-Fermi model is one of the oldest models produced to study different properties of nuclei. Density is a major variable to present both dynamical and statically properties of nuclei in this model. Also, there is no limitation for considering any deformation for nuclei. In This investigation, some major properties of heavy deformed nuclei are investigated using Liquid Drop and Thomas-Fermi model. Considering Quadruple and Hexagonal deformations along with energy improved terms in to nuclear matter, Liquid-Drop parameters containing surface, volume and asymmetry parameters are calculated. Using these parameters, fission barrier high for some heavy deformed nuclei in different temperatures are evaluated. The obtained results compared with experimental data. Comparison indicates that fission barrier high is satisfactory for heavy deformed nuclei. Also, using developed version of this model the precise liquid-drop parameters are obtained so these parameters used to study thermodynamic properties of hot deformed nuclei. Such studies improve knowledge of nuclear physics.
