In this work, the properties of 170-180W isotopes are studied by the E-GOS curves and the
relation between energy levels and E2 showed that 170-180W lie in SU(3)-O(6) transition
region were investigated to calculate the energy levels of ground state band according to the
Interacting Boson Model (IBM-1). The entire calculations and drawing of the figures
implemented by one program written by matlab language. The results are compared with
experimental data and showed good agreement.
