Abstract: (Elsevier)
The effect of the inclusion of both the P 3 and the P 5 degrees of the freedom is describing the potential-energy surface of elements in the lead and actinide region has been investigated. An instability is encountered in the actinide region, particularly so for its lighter members. On the other hand the potential. energy surface of 210 84 Po is found to be stable with respect to asymmetric changes of shape at and near the highest fission barrier peak. These features of the static surface are conjectured to be responsible for the mass distribution of the fission fragments.
