Geoscience for Alaska's D-1 lands: A preliminary report

Theoretical Analysis of Neutron Double-Differential Cross Sections of n + 9 Be Reactions

“…The calculated results agree very well with the experimental measurements as shown in these figures. The comparisons of the calculated results with the double-differential measurements of Schmidt [15] In light nucleus reactions, all of the residual states are discrete levels, therefore, the model calculations are very sensitive to the level schemes. Obviously, the new levels 5.59(3/2 − ) and 6.38(7/2 − ) are added to the level scheme of 9 Be, and the secondary neutron and α particles can be emitted from these two levels, therefore two neutron spectra could be given by each new level.…”

“…There are some double-differential measurements of the total outgoing neutrons for n + 9 Be reaction, such as Ruan [14] and Schmidt. [15] All of the measured data could be used for testing and verifying the light nucleus reaction model.…”
