Behavior of nuclear matter under extreme conditions in fission

The spontaneous fission of Cf-252 has been studied via gamma-gamma-gamma co incidence and gamma-gamma light charged particle coincidence with Gammasphe re. The binary fission yields of correlated Mo-Ba pairs with 0-10 neutron e mission have been remeasured. The existence of "hot" fission mode with 8-1. 0 neutron emission seen previously in the Mo-Ba split is confirmed but with lower intensities. By gating on the light charged particles detected in De ltaE-E detectors and a gamma ray in one partner, the relative yields of cor related pairs in alpha ternary SF with zero to 6n emission are observed for the first time with the distribution peaked at 2.5n. New correlated pairs are identified in Be-10 ternary SF. We observed essentially only cold, On B e-10 and little, if any, hot, xn Be-10. New gamma-gamma-gamma data with 2.3 times the total events show weak non-Doppler broadened high energy peaks i n coincidence with transitions in correlated pairs in Be-10 SF shifted by t he same 6,1 to 26 keV from the 2-0 energy in Be-10 as seen earlier.
