The deformation structure of the even-even ytterbium, hafnium and tungsten nuclei is investigated in framework of the collective model, the single-particle Schrodinger fluid model and the cranked Nilsson model. Accordingly, we have calculated the rotational and vibrational energies, the nuclear moments of inertia, the total ground-state energy, the quadrupole moment, the liquid drop (LD) energy, the Strutinsky inertia, the LD inertia, the volume conservation factor omega(0)/omega(o)(0), the smoothed energy, the Bardeen, Cooper and Schrieffer (BCS) energy and the G-value of the ytterbium: Yb-170, Yb-172 and Yb-174, hafnium: Hf-176, Hf-178 and Hf-180 and tungsten: W-182, W-184 and W-186 nuclei as functions of the deformation parameters beta, gamma, which are assumed to vary in the ranges (-0.50 %26lt;= beta %26lt;= 0.50) and (0 degrees %26lt;= gamma %26lt;= 60 degrees). Also, two polynomials in beta are obtained to produce results in good agreement with the corresponding results for the total ground-state energy and the quadrupole moment of the mentioned nine nuclei.
