  We present a measurement of the ZZ boson-pair production cross section in
1.96 TeV center-of-mass energy ppbar collisions. We reconstruct final states
incorporating four charged leptons or two charged leptons and two neutrinos
from the full data set collected by the Collider Detector experiment at the
Fermilab Tevatron, corresponding to 9.7 fb-1 of integrated luminosity.
Combining the results obtained from each final state, we measure a cross
section of 1.04(+0.32)(-0.25) pb, in good agreement with the standard model
prediction at next-to-leading order in the strong-interaction coupling.
