5.4.4 (n,2n) Reactions
Currently, to evaluate the cross sections of (n,2n) reactions with neutron energy
near 14.6 MeV, empirical and semiempirical formulas and approaches based on
the systematics of experimental data for cross section nuclear reactions are
widely used. In most situations, the parameters of systematic relationships
were identied involving relatively limited number of experimental data, par-
ticularly with large errors.
In spite of the lack of data and the large discrepancies both in the individual
values and in the excitation functions, some rough trends can be recognized
in the cross sections. e plot of (n,2n) cross sections enables establishment of
the following rough trends: ...
