摘要：

By using the statistical theory for neutron-induced light nucleus reaction, the calculation of the neutron double-differential cross sections for n+Be-9 reactions is performed. The secondary outgoing neutrons only coming from the (n,2n)2 alpha reaction channel through six different emission processes are illustrated in detail in this article. Based on the theoretical analysis of neutron double-differential cross sections at E-n=14.1 and 18 MeV, two predicted levels of Be-9, i.e., E(J(pi))Gamma=9(5/2(+))1000 and 10(5/2(+))1000, have been recommended. The calculated results indicate that the fittings would be improved obviously while the predicted levels have been employed.
