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

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