The dynamic deformation model has been used to examine collective features of tungsten isotopes. The magnitudes and signs of calculated Q values as well as the ratios Q${(2\mathrm{}}_{\gamma }^{+}$)/Q${(2\mathrm{}}_g^{+}$) agree well with recent experimental results. The amount of K=0 component in the $2_{\gamma }^{+}$ state is found to be about 10%, but the K=2 component in $2_{\beta }^{+}$ state ranges from 9 to 47 % for the tungsten isotopes A=180–186. A significant K=0, K=2, and K=4 mixing occurs for I≥4 states. Results are supported by published data and also by the X(E0/E2) value for the 792 keV transition between $2_{\gamma }^{+}$ and $2_g^{+}$ states in ${}_{}{}^{18}{}_{}{}^{}\mathrm{W}$.
