Abstract
Coincidence gamma-ray data from the spontaneous fission of Pu-242 were collected at the Lawrence Berkeley Laboratory high purity Ge (HPGe) a rray, GAMMASPHERE. Data from several cold-fission (0 neutron emission) isotopic pairs were observed and are presented. An interesting trend in the fractional population of cold-fission events was observed and i s discussed. Relative yields of Zr-Xe, Sr-Ba, and Mo-Te pairs were mea sured. The Zr-Xe system has the most complete data set. Some speculati ons on the trend in the number of neutrons emitted as a function of th e mass of the Xe isotope populated are presented. Comparisons between the yields from the spontaneous fission of Pu-242 and the yields from thermal-neutron-induced fission of Pu-241 are also presented.
