Abstract
The influence of the entrance channel on fission processes was studied by forming the same composite system by two different target-projectile combinations (40Ar+209Bi and56Fe+187Re, respectively). Compound nucleus fission and quasi fission were observed and the analysis was performed in the framework of the extra-extra-push model, which provides a qualitative interpretation of the results; limits for the extra-extra-push threshold are given, but problems with quantitative predictions for the extra-push are noted.
