It was found that some ternary particle yields obtained from the fissi
on of seven nuclides are correlated to the 2 Z-N values of the compoun
d nuclei. The slopes of the correlations are about the same for the di
fferent ternary particles. It was also found that particles emitted in
cluster radioactivity and particles with the highest yields in ternar
y fission have the highest binding energies per cluster. These observa
tions point to a common relation between cluster radioactivity and ter
nary fission.
