Using a Monte Carlo technique and recent double-differential measurements, a reevaluation of the ⁹Be(n, 2n) reaction has been completed. This evaluation is currently available for use in the most recent evaluation of the Evaluated Nuclear Data Library and will be used in ENDF/B-VI. Calculations have been carried out with these data, and implications for neutron multiplication in beryllium fusion reactor blankets are discussed.
