Correlation between the average prompt neutron multiplicity as a function of the primary mass and the corresponding experimental mass of fragments from 252Cf spontaneous fission

Abstract Using a Monte Carlo simulation, we study the correlations between the average prompt neutron multiplicities as a function of the primary (pre-neutron) mass ν ¯ s ( A ) and the corresponding to the final (post-neutron) mass n ¯ ( m ) and the pseudo mass (obtained by the 2 E method) N ¯ ( μ ) of fragments from the spontaneous fission of 252Cf . We interpret the results in terms of the ratio of neighboring mass yields R A (= Y A + 1 / Y ( A ) ). We find that; i) n ¯ - ν ¯ s is correlated with R - 1 , and ii) N ¯ - ν ¯ s is correlated (anticorrelated) with R - 1 when μ A ( μ > A ).
