Abstract

The concept of fission barrier – a parameter which enters in quantitative estimates of various observables related to nuclear fission – is presented from the point of view of theory based on the picture of nuclear deformation and energy dependent on it. The macroscopic-microscopic method of calculating energy landscapes is presented that is simpler than the self-consistent mean field approach and, due to its two-component nature, seems to be easier to adjust to experimental data. Some models and methods used to find the fission saddles are reviewed. For the purpose of illustration, some results on fission barriers in actinides and superheavy nuclei are shown that were obtained within one macroscopic-microscopic model. Comparisons with results of other models, including some of the mean-field type, are discussed.
