Abstract
The phenomenon of cold (neutronless) binary and ternary fission in spo ntaneous fission of Cf-252 was experimentally observed by triple gamma coincidence technique with Gammasphere with 72 gamma-ray detectors. M any correlated pairs for both binary and ternary (He-4, Be-10) fission were observed in the spontaneous fission of Cf-252. Yields of cold te rnary and cold binary fission were extracted. These results are compar ed with the theoretical calculations using M3Y nucleon-nucleon potenti al and WKB approximation for barrier penetration.
