Ambiguity in extracting the dissipation mechanism
from the experimental systematics of total
kinetic energy of the fission fragments.

Look for oservables that determine univocally the
nature of nuclear dissipation 1)prescission
light particle multiplicities TKE (as
constraint) 2)onset of ternary fission
