Description
The distribution of mass in the spontaneous fission of 252Cf was investigated by the radiochemical determination of the absolute fission yields for 35 mass chains. A summation of the mass-yield curve gives a summed value of 199.4% which is in very good agreement with the value of 200% in fission. The mean masses of the light and heavy group are located at 106.39 and 141.82, respectively. The average number v of neutron per fission is 3.79+-0.12. The peak-to-valley ratio is larger than 370. A comparison of previous data resulted in 'recommended' yields for 35 mass chains. (author)
