now was applied mainly to even-even nuclei [@Kow], to odd-$A$ and odd-odd SH systems. We study a wide range of isotopes which, perhaps, may be of some use for astrophysical purposes. The fission barriers are calculated using the adiabatic assumption, i.e. they are the smallest possible. Since the model has been quite reasonable, in particular in reproducing first [@Kow] and second [@IIbarriers] fission barriers in actinides, as well as super- [@kowskal] and hyper-deformed [@IIIbarriers1; @IIIbarriers2] minima, we prefer to keep its parameters unchanged. The shell and pairing correction for an odd nucleon system is done by blocking the lowest-lying quasiparticle states. The modification of the macroscopic energy by including the average pairing energy contribution which we introduced for nuclear masses in [@JachKowSkal2014] is irrelevant for fission barriers.

The other motivation of our study is to improve the predictions for the fission saddles. This requires simultaneously taking into account a large number of shape variables [@IIbarriers; @IIIbarriers2] and relying on an [*in principle*]{} exact method for finding saddles to escape errors inherent in the mostly used constrained minimization method, see [@Moller2009; @Dubray]. As usual, to make the involved computational effort manageable one has to make some compromises which will be discussed
