Abstract: | The shape parameters of the multiplicity distribution of prompt gamma rays emitted in spontaneous fission of252Cf were obtained using the multiple coincidence technique. The multiplicity distribution is well represented by a Gaussian
distribution. Assuming the average number of prompt gamma rays emitted per fission to be 10.3, the standard deviation of the
multiplicity distribution was estimated to be 4.2±0.4. The variation of the standard deviation of the multiplicity distribution
has also been obtained as a function of kinetic energy of one of the fragments and was found to exhibit a strong zigzag dependence
on the single fragment kinetic energy. The results have been discussed on the basis of the emission mechanism of prompt gamma
rays in fission. |
