Abstract
We present experimental kinetic-energy-release distributions in the asymmetric fission processes and for highly excited mother ions in charge states . We find that the distributions for are considerably narrower and peak at lower energies than for in the corresponding charge state when . Further, semiempirical values for fission barrier heights were extracted for by means of a statistical approach and the measured intensity ratios between fission and evaporation.
