Abstract

Fission-neutron angular correlations following fusion of F19 and Th232 have been measured. Conventional analysis, based on the approximation that post-fission neutrons originate only from fully accelerated fission fragments, gives unexpectedly large numbers of "prefission" neutrons. Comparison with the considerably less fissile system Pb200 gives the first convincing evidence that this approach is inadequate. Consideration of neutron emission from the accelerating fragments gives results consistent with expectations.
