Abstract: $$^{180}$$ 180 Hg is experimentally found to fission asymmetrically. This result was not expected as a naive fragment shell effects study would support the symmetric mode to be the most probable. In the present study we investigate both symmetric and asymmetric $$^{180}$$ 180 Hg fission modes at the mean field level using various multipole moment constraints. Potential energy surfaces are analysed in terms of shell effects that shape their topographies and connections to fragment shell effects are made. The non-occurrence of low energy symmetric fission is interpreted in terms of $$^{90}$$ 90 Zr fragment properties. Throughout this study a comparison with $$^{264}$$ 264 Fm and its symmetric doubly magic $$^{132}$$ 132 Sn fission fragments is done.
